From a8779c2752f27f045f60bb191e257528374dc45c Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 23 Apr 2021 17:19:20 +0200 Subject: [PATCH] media: s3c-camif: use pm_runtime_resume_and_get() 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.
