[PATCH V2 06/16] mmc: omap_hsmmc: introduce start_clock and re-use stop_clock
From: Adrian Hunter <hidden>
Date: 2011-05-06 09:14:05
Also in:
linux-mmc, linux-omap
Subsystem:
multimedia card (mmc), secure digital (sd) and sdio subsystem, omap hs mmc support, the rest · Maintainers:
Ulf Hansson, Linus Torvalds
From: Andy Shevchenko <redacted> 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.
