Subject: intel/blorp: Move the gen7 stencil format workaround to blorp_blit
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=554a1731a52c287c4c387923fea69a98d3a5fc2c;p=mesa.git

intel/blorp: Move the gen7 stencil format workaround to blorp_blit

It's not needed for blorp_copy because it already overrides formats.
It's also not needed for blorp_clear because it clears stencil as
stencil.
