2011-11-23ASoC: skip resume of soc-audio devices without codecsEric Miao1-0/+6
There are cases where there is no working codec on the soc-audio devices, and snd_soc_suspend() will skip such device when suspending.

2011-11-23regulator: TPS65910: Fix VDD1/2 voltage selector countAfzal Mohammed2-7/+10
Count of selector voltage is required for regulator_set_voltage to work via set_voltage_sel. VDD1/2 currently have it as zero, so regulator_set_voltage won't work for VDD1/2. Update count (n_voltages) for VDD1/2. Output Voltage = (step value * 12.5 mV + 562.5 mV) * gain With above expr, number of voltages that can be selected is step value count * gain count constant for gain count will be called VDD1_2_NUM_VOLT_COARSE existing constant for step value count is VDD1_2_NUM_VOLTS, use VDD1_2_NUM_VOLT_FINE instead to make clear that step value is not the only component in deciding selectable voltage count Signed-off-by: Afzal Mohammed <[email protected]> Signed-off-by: Mark Brown <[email protected]>

Just checking the code in cs42l51_fill_cache(): The cache pointer points to codec->reg_cache + 1. I think it is because CS42L51_FIRSTREG is 0x01, so codec->reg_cache[0] is not used here.

2011-11-23ALSA: hda/realtek - Fix missing inits of item indices for auto-micTakashi Iwai1-1/+13
When the imux entries are rebuilt in alc_rebuild_imux_for_auto_mic(), the initialization of index field is missing. It may work without it casually when the original imux was created by the auto-parser, but it's definitely broken in the case of static configs where no imux was parsed beforehand. Because of this, the auto-mic switching doesn't work properly on some model options. This patch adds the missing initialization of index field.

2011-11-23ALSA: hda - Fix invalid pin and GPIO for Apple laptops with CS codecsTakashi Iwai1-9/+23
The PCI SSID 8086:7270 is commonly used for multiple Apple machines, thus we can't use it as identifier for a unique model. Because of this conflict, some machines show weird behavior. For example, MacBook Air shows Front and Surround speakers although only Surround works due to the wrongly overridden pin-configuration for imac27. This patch fixes two things: - Stop the wrong pin-config override of imac27 by removing PCI SSID entry for avoiding the wrong mappings, - Add the generic GPIO setup for Apple machines by checking the codec SSID vendor bits Tested-by: Linus Torvalds <[email protected]> Tested-by: Dirk Hohndel <[email protected]> Signed-off-by: Takashi Iwai <[email protected]>

2011-11-22Revert "of/irq: of_irq_find_parent: check for parent equal to child"Linus Torvalds1-7/+7
This reverts commit dc9372808412edbc653a675a526c2ee6c0c14a91. As requested by Ben Herrenschmidt: "This breaks some powerpc platforms at least. The practice of having a node provide an explicit "interrupt-parent" property pointing to itself is an old trick that we've used in the past to allow a device-node to have interrupts routed to different controllers. In that case, the node also contains an interrupt-map, so the node is its own parent, the interrupt resolution hits the map, which then can route each individual interrupt to a different parent." Grant says: "Ah, nuts, yes that is broken then. Yes, please revert the commit and Rob & I will come up with a better solution. Rob, I think it can be done by explicitly checking for np == desc->interrupt_parent in of_irq_init() instead of relying on of_irq_find_parent() returning NULL."

2011-11-22SUNRPC: Ensure we return EAGAIN in xs_nospace if congestion is clearedTrond Myklebust1-2/+1
By returning '0' instead of 'EAGAIN' when the tests in xs_nospace() fail to find evidence of socket congestion, we are making the RPC engine believe that the message was incorrectly sent and so it disconnects the socket instead of just retrying. The bug appears to have been introduced by commit 5e3771ce2d6a69e10fcc870cdf226d121d868491 (SUNRPC: Ensure that xs_nospace return values are propagated).

2011-11-22percpu: fix chunk range calculationTejun Heo2-20/+26
Percpu allocator recorded the cpus which map to the first and last units in pcpu_first/last_unit_cpu respectively and used them to determine the address range of a chunk - e.g. it assumed that the first unit has the lowest address in a chunk while the last unit has the highest address. This simply isn't true. Groups in a chunk can have arbitrary positive or negative offsets from the previous one and there is no guarantee that the first unit occupies the lowest offset while the last one the highest. Fix it by actually comparing unit offsets to determine cpus occupying the lowest and highest offsets. Also, rename pcu_first/last_unit_cpu to pcpu_low/high_unit_cpu to avoid confusion. The chunk address range is used to flush cache on vmalloc area map/unmap and decide whether a given address is in the first chunk by per_cpu_ptr_to_phys() and the bug was discovered by invalid per_cpu_ptr_to_phys() translation for crash_note.

2011-11-22ALSA: lx6464es - fix device communication via command busTim Blechmann1-4/+12
commit 6175ddf06b6172046a329e3abfd9c901a43efd2e optimized the mem*io functions that have been used to send commands to the device. these optimizations somehow corrupted the communication with the lx6464es, that resulted the device to be unusable with kernels after 2.6.33. this patch emulates the memcpy_*_io functions via a loop to avoid these problems.
