[PATCH 5.10 212/593] media: s5p_cec: decrement usage count if disabled

[Greg Kroah-Hartman]

From: Mauro Carvalho Chehab <mchehab+huawei@xxxxxxxxxx>

[ Upstream commit 747bad54a677d8633ec14b39dfbeb859c821d7f2 ]

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.
