Subject: pvr: Zero init pbe_cs_words to avoid passing on garbage.
X-Git-Tag: upstream/22.3.5~2098
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1021550e202b1088e24070f6363b4b0c437b38a4;p=platform%2Fupstream%2Fmesa.git

pvr: Zero init pbe_cs_words to avoid passing on garbage.

In case if the surface->resolve_type is not PVR_RESOLVE_TYPE_PBE
then we do not setup pbe_cs_words in which case we might end up
using garbage values.

Fixes: CID 1515466.
