Subject: [PATCH V2 08/16] mmc: omap_hsmmc: split same pieces of code to separate functions
Date: Fri,  6 May 2011 12:14:07 +0300	[thread overview]
Message-ID: <1304673255-31634-9-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 are few places with the same functionality. This patch creates two
functions omap_hsmmc_set_bus_width() and omap_hsmmc_set_bus_mode() to do the
job.
