Subject: [PATCH 3/4] usb: hub: rename *kick_khubd to *kick_hub_wq
Date: Fri, 12 Sep 2014 14:21:07 +0200	[thread overview]
Message-ID: <1410524468-15232-4-git-send-email-pmladek@suse.cz> (raw)
In-Reply-To: <1410524468-15232-1-git-send-email-pmladek@suse.cz>

USB hub started to use a workqueue instead of kthread. Let's make it clear from
the function names.
