[PATCH 3/3] firmware: qcom: scm: Return PTR_ERR when devm_clk_get fails

When devm_clk_get fails for core clock, the failure was ignored and the core_clk was explicitly set to NULL so that other remaining clocks can be queried. However, now that we have a clean way of expressing the clock dependency, return failure when devm_clk_get fails for core clock.

[PATCH 0/3] Remove clocks dependency from SCM driver

On earlier chiptsets (APQ8064, MSM8660, MSM8690, MSM8916, APQ8084, MSM8974) crypto operations of TZ were depends on crypto clocks controlled by users/clients. However on MSM8996 crypto clocks control is handled internally in TZ itself. The current series of patches handle this clock dependency in

[PATCH 1/2] block: immediately dispatch big size request

Currently block plug holds up to 16 non-mergeable requests. This makes sense if the request size is small, eg, reduce lock contention. But if request size is big enough, we don't need to worry about lock contention. Holding such request makes no sense and it lows the disk utilization. In

[PATCH 5/6] Input: gpio_keys - add support for GPIO descriptors

From: Geert Uytterhoeven GPIO descriptors are the preferred way over legacy GPIO numbers nowadays. Convert the driver to use GPIO descriptors internally but still allow passing legacy GPIO numbers from platform data to support existing platforms. Based on commits

[PATCH 2/6] Input: gpio_keys_polled - always use gpiod_get_value_cansleep

It does not matter if given GPIO may sleep or not when reading state, polling is always done in a non-atomic context, so we should always be able to simply use gpiod_get_value_cansleep(). Also let's note in the logs when we fail to read gpio state. Reviewed-by: Hans de Goede
