Subject: [PATCH V2 06/16] mmc: omap_hsmmc: introduce start_clock and re-use stop_clock
Date: Fri, 6 May 2011 12:14:05 +0300 [thread overview]
Message-ID: <1304673255-31634-7-git-send-email-adrian.hunter@nokia.com> (raw)
In-Reply-To: <1304673255-31634-1-git-send-email-adrian.hunter@nokia.com>
From: Andy Shevchenko <ext-andriy.shevchenko@nokia.com>
There is similar piece of code in two functions which enables clock. Split this
code to omap_hsmmc_start_clock(). Re-use omap_hsmmc_stop_clock() in
omap_hsmmc_context_restore() as well.
