Subject: st/nine: Ignore MULTISAMPLEMASK when RT is not multisampled
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=85811d0e87b4e460a1cf4cc6654482c05628c383;p=mesa.git

st/nine: Ignore MULTISAMPLEMASK when RT is not multisampled

We were ignoring MULTISAMPLEMASK for non-maskable multisample
modes, but we were missing the non-multisampled case.

Fixes a crash in Halo.
