Subject: drm/i915: clean up udelay usage
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=580982d399071474c349538b7f5780bc79b54e7f;p=linux-beck.git

drm/i915: clean up udelay usage

udelay() of 20 milliseconds really ought to just use mdelay(), that avoids
the various wrap scenarios and also is more readable
