From mboxrd@z Thu Jan 1 00:00:00 1970 From: adrian.hunter@nokia.com (Adrian Hunter) Date: Fri, 6 May 2011 12:14:05 +0300 Subject: [PATCH V2 06/16] mmc: omap_hsmmc: introduce start_clock and re-use stop_clock In-Reply-To: <1304673255-31634-1-git-send-email-adrian.hunter@nokia.com> References: <1304673255-31634-1-git-send-email-adrian.hunter@nokia.com> Message-ID: <1304673255-31634-7-git-send-email-adrian.hunter@nokia.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Andy Shevchenko 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.
