Subject: [PATCH] media: s5p_cec: decrement usage count if disabled
Git-commit: 747bad54a677d8633ec14b39dfbeb859c821d7f2
References: git-fixes
Patch-mainline: v5.14-rc1

There's a bug at s5p_cec_adap_enable(): if called to
disable the device, it should call pm_runtime_put()
instead of pm_runtime_disable(), as the goal here is to
decrement the usage_count and not to disable PM runtime.
