2021-03-15scmi-cpufreq: Remove deferred probeNicola Mazzucato1-2/+4
The current implementation of the scmi_cpufreq_init() function returns -EPROBE_DEFER when the OPP table is not populated. In practice the cpufreq core cannot handle this error code. Therefore, fix the return value and clarify the error message.

2021-03-10PCI: pci-dra7xx: Prepare for deferred probe with module_platform_driverTony Lindgren1-6/+7
After updating pci-dra7xx driver to probe with ti-sysc and genpd, I noticed that dra7xx_pcie_probe() would not run if a power-domains property was configured for the interconnect target module. Turns out that module_platform_driver_probe uses platform_driver_probe(), while builtin_platform_driver uses platform_driver_register(). Only platform_driver_register() works for deferred probe as noted in the comments for __platform_driver_probe() in drivers/base/platform.c with a line saying "Note that this is incompatible with deferred probing". With module_platform_driver_probe, we have platform_driver_probe() produce -ENODEV error at device_initcall() level, and no further attempts are done. Let's fix this by using module_platform_driver instead. Note this is not an issue currently as we probe devices with simple-bus, and only is needed as we start probing the device with ti-sysc, or when probed with simple-pm-bus. Note that we must now also remove __init for probe related functions to avoid a section mismatch warning.

2021-03-10soc: ti: omap-prm: Allow hardware supported retention when idleTony Lindgren1-4/+12
When moving the l4 interconnect instances to probe with simple-pm-bus and genpd, we will have l4per and core domains stop idling unless we configure the domain bits to allow retention when idle. As the TI SoCs have hardware autoidle capabilities, this is safe to do. The domains will only enter retention on WFI when none of the devices on the domain block autoidle in the hardware. This follows what we are already currently doing. Cc: Santosh Shilimkar <[email protected]> Cc: Tero Kristo <[email protected]> Signed-off-by: Tony Lindgren <[email protected]>

2021-03-08soc: renesas: rmobile-sysc: Mark fwnode when PM domain is addedGeert Uytterhoeven1-0/+2
Currently, there are two drivers binding to the R-Mobile System Controller (SYSC): - The rmobile-sysc driver registers PM domains from a core_initcall(), and does not use a platform driver, - The optional rmobile-reset driver registers a reset handler, and does use a platform driver. As fw_devlink only considers devices, commit bab2d712eeaf9d60 ("PM: domains: Mark fwnodes when their powerdomain is added/removed") works only for PM Domain drivers where the DT node is a real device node, and not for PM Domain drivers using a hierarchical representation inside a subnode. Hence if fw_devlink is enabled, probing of on-chip devices that are part of the SYSC PM domain is deferred until the optional rmobile-reset driver has been bound. If the rmobile-reset driver is not available, this will never happen, and thus lead to complete system boot failures. Fix this by explicitly marking the fwnode initialized.

Non-functional fixes: - Fix help text in Kconfig - Remove duplicate prototype for trace_empty() - Fix stale comment about the trace_event_call flags. Self test update: - Add more information to the validation output of when a corrupt timestamp is found in the ring buffer, and also trigger a warning to make sure that tests catch it" * tag 'trace-v5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Fix comment about the trace_event_call flags tracing: Skip selftests if tracing is disabled tracing: Fix memory leak in __create_synth_event() ring-buffer: Add a little more information and a WARN when time stamp going backwards is detected ring-buffer: Force before_stamp and write_stamp to be different on discard tracing: Fix help text of TRACEPOINT_BENCHMARK in Kconfig tracing: Remove duplicate declaration from trace.h ftrace: Have recordmcount use w8 to read relp->r_info in arm64_is_fake_mcount
2021-03-05RDMA/rxe: Fix errant WARN_ONCE in rxe_completer()Bob Pearson1-32/+23
In rxe_comp.c in rxe_completer() the function free_pkt() did not clear skb which triggered a warning at 'done:' and could possibly at 'exit:'. The WARN_ONCE() calls are not actually needed. The call to free_pkt() is moved to the end to clearly show that all skbs are freed.

2021-03-05RDMA/rxe: Fix extra deref in rxe_rcv_mcast_pkt()Bob Pearson1-24/+35
rxe_rcv_mcast_pkt() dropped a reference to ib_device when no error occurred causing an underflow on the reference counter. This code is cleaned up to be clearer and easier to read.

2021-03-05RDMA/rxe: Fix missed IB reference counting in loopbackBob Pearson1-1/+9
When the noted patch below extending the reference taken by rxe_get_dev_from_net() in rxe_udp_encap_recv() until each skb is freed it was not matched by a reference in the loopback path resulting in underflows.

2021-03-05io_uring: don't restrict issue_flags for io_openatPavel Begunkov1-1/+1
45d189c606292 ("io_uring: replace force_nonblock with flags") did something strange for io_openat() slicing all issue_flags but IO_URING_F_NONBLOCK. Not a bug for now, but better to just forward the flags. Signed-off-by: Pavel Begunkov <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
