| From | Mauro Carvalho Chehab <> | Subject | [PATCH v2 48/79] media: i2c: ov5647: use pm_runtime_resume_and_get() | Date | Tue, 27 Apr 2021 12:13:15 +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.
