[PATCH v3 2/2] remoteproc: Modify recovery path to use rproc_{start,stop}()

[PATCH v3 1/2] remoteproc: Introduce rproc_{start,stop}() functions

In the context of recovering from crash, rproc_trigger_recovery() does rproc_shutdown() followed by rproc_boot(). The remoteproc resources are cleaned up in rproc_shutdown() and immediately reallocated in rproc_boot() which is an unnecessary overhead. Furthermore, we want the memory regions to be

[RFC PATCH v3 4/5] ACPI: button: Fix lid notification

In acpi_lid_notify_state(), it now contains logic to avoid frequently replayed events which originally was ensured by using blocking notifier. On the contrary, using blocking notifier is wrong as it could keep on returning NOTIFY_DONE, causing events lost. This patch thus changes lid notification

[RFC PATCH v3 5/5] ACPI: button: Always notify kernel space using _LID returning value

Both nouveau and i915, the only 2 kernel space lid notification listeners, invoke acpi_lid_open() API to obtain _LID returning value instead of using the notified value. So this patch moves this logic from listeners to lid driver, always notify kernel space listeners using _LID returning value.

[PATCH] staging: iio: ad7152: Fix deadlock in ad7152_write_raw_samp_freq()
