[PATCH 00/13] PM: runtime: Convert pm_runtime_put_autosuspend() and friends to a void function

by Brian Norris

Similar to this effort: Subject: [PATCH v1 00/23] PM: runtime: Convert pm_runtime_put() to a void function https://lore.kernel.org/all/6245770.lOV4Wx5bFT@rafael.j.wysocki/ i.e., commit 3afd8df02433 ("PM: runtime: Change pm_runtime_put() return type to void") and friends. As with pm_runtime_put(), there is very little value in return-code checking for any of the other async __pm_runtime_suspend() and __pm_runtime_idle() APIs: pm_runtime_put_autosuspend() pm_request_idle() pm_request_autosuspend() Checking the return code is more likely to produce a race condition (fighting with user space writing "on" to the "control" attribute) than to tell a consumer useful info. Nobody outside KUnit tests checks pm_request_idle() or pm_request_autosuspend() return codes, but there are a number of pm_runtime_put_autosuspend() callers that check its return code. Thus, this series largely deals with pm_runtime_put_autosuspend(). Patches 1-11 are independent of each other, and similarly to the last series, I expect the respective maintainers can pick them up. We can apply patch 12 later. Patch 13 is also independent, but included in this topic for completeness. It can be applied any time. This touches a lot of trees/maintainers, so I tried to keep CC's only for the relevant patch(es), plus the cover letter. I hope that's not too noisy. - Brian Brian Norris (13): hwrng: cctrng: Discard pm_runtime_put_autosuspend() return value drm: Discard pm_runtime_put_autosuspend() return values iio: Discard pm_runtime_put_autosuspend() return values media: venus: Discard pm_runtime_put_autosuspend() return values pinctrl: qcom: lpass-lpi: Discard pm_runtime_put_autosuspend() return values spi: ti-qspi: Discard pm_runtime_put_autosuspend() return value greybus: Discard pm_runtime_put_autosuspend() return value ALSA: hda: Discard pm_runtime_put_autosuspend() return value ASoC: codecs: lpass: Discard pm_runtime_put_autosuspend() return values ASoC: intel: atom: Discard pm_runtime_put_autosuspend() return value ASoC: SOF: Discard pm_runtime_put_autosuspend() return values PM: runtime: Drop pm_runtime_put_autosuspend() return code PM: runtime: Drop pm_request_{idle,autosuspend}() return codes drivers/base/power/runtime-test.c | 8 --- drivers/char/hw_random/cctrng.c | 6 +- drivers/gpu/drm/panel/panel-simple.c | 8 +-- drivers/gpu/drm/tidss/tidss_drv.c | 7 +-- drivers/gpu/drm/v3d/v3d_drv.h | 4 +- drivers/iio/accel/bmc150-accel-core.c | 14 ++--- drivers/iio/accel/fxls8962af-core.c | 11 +--- drivers/iio/accel/kxcjk-1013.c | 15 ++--- drivers/iio/accel/mma8452.c | 15 +++-- drivers/iio/accel/mma9551_core.c | 15 +++-- drivers/iio/adc/rcar-gyroadc.c | 4 +- drivers/iio/adc/ti-ads1015.c | 8 +-- drivers/iio/chemical/atlas-sensor.c | 4 +- .../common/hid-sensors/hid-sensor-trigger.c | 14 ++--- drivers/iio/gyro/bmg160_core.c | 17 +++-- drivers/iio/gyro/fxas21002c_core.c | 12 ++-- drivers/iio/imu/kmx61.c | 17 +++-- drivers/iio/light/apds9960.c | 2 +- drivers/iio/light/isl29028.c | 15 +---- drivers/iio/light/pa12203001.c | 3 +- drivers/iio/light/rpr0521.c | 15 +++-- drivers/iio/light/tsl2583.c | 27 ++------ drivers/iio/light/us5182d.c | 3 +- drivers/media/platform/qcom/venus/vdec.c | 10 ++- drivers/media/platform/qcom/venus/venc.c | 10 ++- drivers/pinctrl/qcom/pinctrl-lpass-lpi.c | 16 +++-- drivers/spi/spi-ti-qspi.c | 6 +- drivers/staging/greybus/power_supply.c | 8 +-- include/linux/greybus/bundle.h | 12 +--- include/linux/pm_runtime.h | 63 +++---------------- include/sound/hdaudio.h | 8 +-- sound/hda/core/device.c | 13 ++-- sound/soc/codecs/lpass-rx-macro.c | 4 +- sound/soc/codecs/lpass-tx-macro.c | 4 +- sound/soc/codecs/lpass-va-macro.c | 17 ++--- sound/soc/codecs/lpass-wsa-macro.c | 8 +-- sound/soc/intel/atom/sst/sst.h | 2 +- sound/soc/intel/atom/sst/sst_drv_interface.c | 4 +- sound/soc/intel/atom/sst/sst_pvt.c | 9 +-- sound/soc/sof/control.c | 6 +- sound/soc/sof/sof-client-ipc-flood-test.c | 5 +- .../soc/sof/sof-client-ipc-kernel-injector.c | 4 +- sound/soc/sof/sof-client-ipc-msg-injector.c | 6 +- sound/soc/sof/sof-client-probes.c | 18 ++---- 44 files changed, 152 insertions(+), 325 deletions(-) -- 2.56.0.360.g66cac248cb-goog

[PATCH] staging: greybus: audio: do not use iterator after list loop

by Rahul Rao

Using the list iterator variable outside the loop breaks iterator scope semantics and can result in invalid memory access if the loop completes without finding a match. Introduce a dedicated iterator variable 'iter' for traversing codec->module_list and assign it to 'module' only upon finding a match.
