From 762476fa24df17914e1a8fab42e12d59da87539a Mon Sep 17 00:00:00 2001 From: Todd Poynor Date: Mon, 11 Oct 2010 16:51:28 -0700 Subject: [PATCH] sdhci: Always pass clock request value zero to set_clock host op To allow the set_clock host op to disable the SDCLK source when not needed, always call the host op when the requested clock speed is zero. Do this even if host->clock already equals zero, because the SDHCI driver may set that value (without calling the host op) to force an update at the next (non-zero-speed) call.
