Subject: broadcom/vc5: Fix cpp of MSAA surfaces on 4.x.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9f3f4284c0397615bfe50ba4e50aaffe5dc64e84;p=mesa.git

broadcom/vc5: Fix cpp of MSAA surfaces on 4.x.

The internal-type-bpp path is for surfaces that get stored in the raw TLB
format.  For 4.x, we're storing MSAA as just 2x width/height at the
original format.
