Subject: radeonsi: don't call force_dcc_off for buffers
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=35c3cbad3c30ad3d40a6811dd6ca2286e013bfc5;p=mesa.git

radeonsi: don't call force_dcc_off for buffers

This was undefined yet harmless behavior in LLVM.
Not anymore - it causes a hang now.
