Subject: [PATCH] mfd: wm8994: Cache chip revision
Date: Thu, 5 Apr 2012 15:16:56 +0100 [thread overview]
Message-ID: <1333635416-3905-1-git-send-email-broonie@opensource.wolfsonmicro.com> (raw)
There's no need to mark the chip revision registers as volatile, it won't
change at runtime so we can cache it from the device at startup.
