From 7295e537bb2b16b500ff55cd6209b3cefd323948 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 23 Apr 2021 17:19:17 +0200 Subject: [PATCH] media: coda: 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. While here, as noted by Phillip, the labels at the coda_open() function are currently named after what operation failed, instead of what they do in response. So, change the name of the error label that it is called when clk_enable fails, in order to be consistent.
