Subject: [PATCH 2/4] mmc: core: make erase timeout calculation allow for gated clock
Date: Thu, 23 Jun 2011 13:40:27 +0300	[thread overview]
Message-ID: <1308825629-27375-3-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1308825629-27375-1-git-send-email-adrian.hunter@intel.com>

The erase timeout calculation may depend on clock rate
which is zero if the clock is gated, so use
mmc_host_clk_rate() which allows for that case.
