From e0c7f99b863b485ad0cde371ea1f62ec8ff70c5d Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 6 May 2011 12:14:05 +0300 Subject: [PATCH] mmc: omap_hsmmc: introduce start_clock and re-use stop_clock There is similar code in two functions which enable the clock. Refactor this code to omap_hsmmc_start_clock(). Re-use omap_hsmmc_stop_clock() in omap_hsmmc_context_restore() as well.
