Subject: i915: Fix GR register array size off-by-one bug
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=123f794fa7d592644881a20801638d88521d0b06;p=openwrt%2Fstaging%2Fblogic.git

i915: Fix GR register array size off-by-one bug

Make sure we have enough room for all the GR registers or we'll end up
clobbering the AR index register (which should actually be harmless
unless the BIOS is making an assumption about it).
