[PATCH 2/5] hwrng: exynos - Runtime suspend device after init

The driver uses pm_runtime_put_noidle() after initialization so the device might remain in active state if the core does not read from it (the read callback contains regular runtime put). The put_noidle() was chosen probably to avoid unneeded suspend and resume cycle after the initialization.

[PATCH 5/5] hwrng: exynos - Disable runtime PM on driver unbind

Driver enabled runtime PM but did not revert this on removal. Re-binding of a device triggered warning: exynos-rng 10830400.rng: Unbalanced pm_runtime_enable! Fixes: b329669ea0b5 ("hwrng: exynos - Add support for Exynos random number generator") Signed-off-by: Krzysztof Kozlowski

[PATCH 4/5] hwrng: exynos - Disable runtime PM on probe failure

Add proper error path (for disabling runtime PM) when registering of hwrng fails. Fixes: b329669ea0b5 ("hwrng: exynos - Add support for Exynos random number generator") Signed-off-by: Krzysztof Kozlowski --- drivers/char/hw_random/exynos-rng.c | 7 ++- 1 file

[PATCH 3/5] hwrng: exynos - Fix unbalanced PM runtime put on timeout error path

In case of timeout during read operation, the exit path lacked PM runtime put. This could lead to unbalanced runtime PM usage counter thus leaving the device in an active state. Fixes: d7fd6075a205 ("hwrng: exynos - Add timeout for waiting on init done") Cc: # v4.4+

[PATCH 1/5] hwrng: exynos - Hide PM functions with __maybe_unused

Replace ifdef with __maybe_unused to silence compiler warning on when SUSPEND=n and PM=y: drivers/char/hw_random/exynos-rng.c:166:12: warning: ‘exynos_rng_suspend’ defined but not used [-Wunused-function] static int exynos_rng_suspend(struct device *dev) ^
