Subject: drm/i915: fix subslice mask array size
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cf303a41d97e3fd5c70c5d8a61a11ce7db7e559f;p=linux.git

drm/i915: fix subslice mask array size

We have a subslice mask per slice, not per subslice.
MAX_SUBSLICES > MAX_SLICES, so the wrong size didn't cause any issue
apart from using extra memory.
