Subject: radv: handle final layouts at end of every subpass and render pass
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b509013060b14e6cbbdbe39964003f1c4f3169d1;p=mesa.git

radv: handle final layouts at end of every subpass and render pass

That shouldn't change anything as we check if the last
subpass id is the final subpass.
