Subject: [PATCH] driver core: Add missing pm_runtime_put_noidle
Date: Mon, 17 Jan 2022 03:07:03 -0800 [thread overview]
Message-ID: <1642417623-5393-1-git-send-email-lyz_cs@pku.edu.cn> (raw)
pm_runtime_get_noresume() in device_shutdown increments the
runtime PM usage counter, thus a matching decrement is needed
to keep the counter balanced.
