Subject: drm/amd/display: Fix warning. Set MAX_SURFACES to 3
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=091a97e542cf9a9af6e48aa1324044433ea7341a;p=openwrt%2Fstaging%2Fblogic.git

drm/amd/display: Fix warning. Set MAX_SURFACES to 3

Currently we never use more than 2 surfaces in all use cases.
This avoids pushing dc_commit_surfaces_to_target beyond a
stacksize of 1024.
