Subject: media: stm32: use pm_runtime_resume_and_get() Author: Mauro Carvalho Chehab <[email protected]> Date: Fri Apr 23 17:19:21 2021 +0200 Commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter") added pm_runtime_resume_and_get() in order to automatically handle dev->power.usage_count decrement on errors. Use the new API, in order to cleanup the error check logic.
