[PATCH v2 1/2] [media] exynos-gsc: Fix unbalanced pm_runtime_enable() error
From: Javier Martinez Canillas
Date: Thu Jan 19 2017 - 17:36:40 EST
Commit a006c04e6218 ("[media] exynos-gsc: Fixup clock management at
->remove()") changed the driver's .remove function logic to fist do
a pm_runtime_get_sync() to make sure the device is powered before
attempting to gate the gsc clock.
But the commit also removed a pm_runtime_disable() call that leads
to an unbalanced pm_runtime_enable() error if the driver is removed
and re-probed:
exynos-gsc 13e00000.video-scaler: Unbalanced pm_runtime_enable!
exynos-gsc 13e10000.video-scaler: Unbalanced pm_runtime_enable!
Fixes: a006c04e6218 ("[media] exynos-gsc: Fixup clock management at ->remove()")
