Subject: [PATCH] hotplug: unlock in error path in acpiphp_enable_slot
Date: Sat, 23 Jan 2016 15:44:19 -0500 [thread overview]
Message-ID: <1453581859-19565-1-git-send-email-wuninsu@gmail.com> (raw)
In acpiphp_enable_slot, there is a missing unlock path
when error occurred. It needs to be unlocked before returning an error.
