Subject: [PATCH 15/27] ALSA: hda - Use timecounter_initialize interface
Date: Fri, 15 Dec 2017 13:08:30 +0530	[thread overview]
Message-ID: <1513323522-15021-16-git-send-email-sagar.a.kamble@intel.com> (raw)
In-Reply-To: <1513323522-15021-1-git-send-email-sagar.a.kamble@intel.com>

With new interface timecounter_initialize we can initialize timecounter
fields and underlying cyclecounter together. Update azx timecounter
init with this new function.
