Subject: regulator: core.c Only delay when setting voltage requires this
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=8b96de31b0cf190fb6b21c4ab1ce310c430b72ae;p=deliverable%2Flinux.git

regulator: core.c Only delay when setting voltage requires this

minor optimization: move delay code to where delay is set and
thus where it is used vs in the main line path.
