[PATCH v3 19/79] media: sun8i_rotate: fix pm_runtime_get_sync() usage count
From: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
Date: 2021-04-27 10:29:21
Also in:
linux-media, lkml
Subsystem:
media input infrastructure (v4l/dvb), rotation driver for allwinner a83t, the rest · Maintainers:
Mauro Carvalho Chehab, Jernej Skrabec, Linus Torvalds
The pm_runtime_get_sync() internally increments the
dev->power.usage_count without decrementing it, even on errors.
Replace it by the new pm_runtime_resume_and_get(), introduced by:
commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")
in order to properly decrement the usage counter and avoid memory
leaks.
