+Subject: pcf50633 remove suspend_enable/disable regulator functions
+X-Git-Tag: fork-to-stable-2.6.29-rc2~142
+X-Git-Url: http://git.openmoko.org/?p=kernel.git;a=commitdiff_plain;h=276709515c384f4239c9479b56fcf008ae37eec8
+
+pcf50633 remove suspend_enable/disable regulator functions
+
+Since we don't switch to PMU.standby, on suspend we should not
+be defining these.
+
+Btw, this fixes the WSOD I observed on andy-tracking and also
+gets rid of the regulator related backtrace seen upon resume.
