Subject: r600g: fixup PS_PARTIAL_FLUSH flag handling for cayman
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8b5acad0e985215b46fc1cfc8ad87c8771a11a3a;p=mesa.git

r600g: fixup PS_PARTIAL_FLUSH flag handling for cayman

So we don't emit it twice if we ever use the flag on
cayman.

Note: this is a candidate for the 9.1 branch.
