2021-01-21driver core: Fix device link device name collisionSaravana Kannan5-18/+35
The device link device's name was of the form: <supplier-dev-name>--<consumer-dev-name> This can cause name collision as reported here [1] as device names are not globally unique. Since device names have to be unique within the bus/class, add the bus/class name as a prefix to the device names used to construct the device link device name. So the devuce link device's name will be of the form: <supplier-bus-name>:<supplier-dev-name>--<consumer-bus-name>:<consumer-dev-name> [1] - https://lore.kernel.org/lkml/[email protected]/ Fixes: 287905e68dd2 ("driver core: Expose device link details in sysfs") Cc: [email protected] Reported-by: Michael Walle <[email protected]> Tested-by: Michael Walle <[email protected]> Signed-off-by: Saravana Kannan <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>

If the device passed as the target (second argument) to device_is_dependent() is not completely registered (that is, it has been initialized, but not added yet), but the parent pointer of it is set, it may be missing from the list of the parent's children and device_for_each_child() called by device_is_dependent() cannot be relied on to catch that dependency. For this reason, modify device_is_dependent() to check the ancestors of the target device by following its parent pointer in addition to the device_for_each_child() walk.

Let's change the number of channels to be 3 instead of 4 so the math works out to have a max register of 0x67010, nicely fitting inside of the region size of 0x68000. Note: I tried to bump up the size of the register region to the next page to include the 0x68010 register but then the tail command caused SErrors with an async abort, implying that the register region doesn't exist or it isn't clocked because the bus is telling us that the register read failed. I reduce the number of channels and played audio through the HDMI channel and it kept working so I think this is correct.

2021-01-21x86/fpu: Add kernel_fpu_begin_mask() to selectively initialize stateAndy Lutomirski2-6/+18
Currently, requesting kernel FPU access doesn't distinguish which parts of the extended ("FPU") state are needed. This is nice for simplicity, but there are a few cases in which it's suboptimal: - The vast majority of in-kernel FPU users want XMM/YMM/ZMM state but do not use legacy 387 state. These users want MXCSR initialized but don't care about the FPU control word. Skipping FNINIT would save time. (Empirically, FNINIT is several times slower than LDMXCSR.) - Code that wants MMX doesn't want or need MXCSR initialized. _mmx_memcpy(), for example, can run before CR4.OSFXSR gets set, and initializing MXCSR will fail because LDMXCSR generates an #UD when the aforementioned CR4 bit is not set. - Any future in-kernel users of XFD (eXtended Feature Disable)-capable dynamic states will need special handling. Add a more specific API that allows callers to specify exactly what they want.

<[email protected]>: LPASS driver is partially broken on DragonBoard DB410c on 5.10 and its totally broken on other Supported Qualcomm SoCs. This was due to DAI ids being over written by the SoC specific header files in the dt-bindings. Idea of having SoC specific headers is not doable when we are dealing with a common driver. So this patchset attempts to fix this properly by creating a common dt-bindings header for lpass which can be updated with new entries if required. This patchset also add an simple of_xlate function to resolve the dai names and different SoCs might not have 1:1 mapping for the dai_driver array with dai ids. Changes since v1: - removed array indexes as suggested by Stephan G. - rebased to sound/for-next branch - collected Srinivasa tested-by tag for sc7180 platform.

2021-01-21Merge series "Add KUNIT tests for ASoC topology" from Amadeusz ↵Mark Brown1-4/+5
Sławiński<[email protected]>: This series adds unit tests for ASoC topology. First fix problems found when developing and running test cases and then add tests implementation. Tests themselves are quite simple and just call snd_soc_tplg_component_load() with various parameters and check the result. Tests themselves are described in more detail in commits adding them. Goal is to expand the amount of test cases in following patches. Prerequisity for this patchset are 2 patches which have already been sent: https://lore.kernel.org/alsa-devel/[email protected]/T/#t Description on how typical test case itself works: In order to load topology we need to have 3 things: card, codec component & platform component. In typical test case we register card and platform component and bind to dummy codec. There are of course execeptions, when we want to test behaviour of topology API when component or card is missing. Note that this is bit different from typical scenario (in SOF and skylake drivers) where card is registered by machine driver and component by platform driver, as we register both when setting up test. If you check the test case most of them have similar architecture of: 1. /* run test */ ret = snd_soc_register_card(&kunit_comp->card); if (ret != 0 && ret != -EPROBE_DEFER) KUNIT_FAIL(test, "Failed to register card"); 2. ret = snd_soc_component_initialize(&kunit_comp->comp, &test_component, test_dev); KUNIT_EXPECT_EQ(test, 0, ret); 3. ret = snd_soc_add_component(&kunit_comp->comp, NULL, 0); KUNIT_EXPECT_EQ(test, 0, ret); Ad. 1. First we register card, which in most tests returns -EPROBE_DEFER (from snd_soc_bind_card()), as platform component is not yet created. I test for both 0 and -EPROBE_DEFER, as it makes it easier to reshuffle this code around if needed and there is one test case which does it in different order. Ad. 2. Then we initialize platform component with structure pointing at proper probe function, which calls snd_soc_tplg_component_load() with test parameters and checks expected result. Ad. 3. And then in follow up we call snd_soc_add_component() which creates platform component for us and calls snd_soc_try_rebind_card() which if everything is bound properly calls previously set probe function.

2021-01-20mtd: rawnand: omap: Use BCH private fields in the specific OOB layoutMiquel Raynal1-6/+9
The OMAP driver may leverage software BCH logic to locate errors while using its own hardware to detect the presence of errors. This is achieved with a "mixed" mode which initializes manually the software BCH internal logic while providing its own OOB layout. The issue here comes from the fact that the BCH driver has been updated to only use generic NAND objects, and no longer depend on raw NAND structures as it is usable from SPI-NAND as well. However, at the end of the BCH context initialization, the driver checks the validity of the OOB layout. At this stage, the raw NAND fields have not been populated yet while being used by the layout helpers, leading to an invalid layout. The chosen solution here is to include the BCH structure definition and to refer to the BCH fields directly (de-referenced as a const pointer here) to know as early as possible the number of steps and ECC bytes which have been chosen. Note: I don't know which commit exactly triggered the error, but the entire migration to a generic BCH driver got merged in one go, so this should not be a problem for stable backports.

2021-01-20ALSA: usb-audio: Fix hw constraints dependenciesTakashi Iwai1-0/+3
Since the recent refactoring, it's been reported that some USB-audio devices (typically webcams) are no longer detected properly by PulseAudio. The debug session revealed that it's failing at probing by PA to try the sample rate 44.1kHz while the device has discrete sample rates other than 44.1kHz. But the puzzle was that arecord works as is, and some other devices with the discrete rates work, either. After all, this turned out to be the lack of the dependencies in a few hw constraint rules: snd_pcm_hw_rule_add() has the (variable) arguments specifying the dependent parameters, and some functions didn't set the target parameter itself as the dependencies. This resulted in an invalid parameter that could be generated only in a certain call pattern. This bug itself has been present in the code, but it didn't trigger errors just because the rules were casually avoiding such a corner case. After the recent refactoring and cleanup, however, the hw constraints work "as expected", and the problem surfaced now. For fixing the problem above, this patch adds the missing dependent parameters to each snd_pcm_hw_rule() call.

We've recently had 2 cases where callers of acpi_bus_get_device() did not properly error check the return value, so set the returned- by-reference acpi_device pointer to NULL, because at least some callers of acpi_bus_get_device() expect that to be done on errors.
