Subject: [PATCH 06/10] ALSA: aloop: Rename all jiffies timer specific functions
Date: Tue, 26 Mar 2019 08:49:30 +0100 [thread overview]
Message-ID: <1553586574-18608-2-git-send-email-twischer@de.adit-jv.com> (raw)
In-Reply-To: <1553586574-18608-1-git-send-email-twischer@de.adit-jv.com>
From: Timo Wischer <twischer@de.adit-jv.com>
This commit does not change the behaviour. It only seperates the jiffies
timer specific implementation from the generic part.
