Subject: vc4: Use vc4_setup_slices for resource import
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bb466a996ffcd328d7f4b543a202291913800979;p=mesa.git

vc4: Use vc4_setup_slices for resource import

Rather than open-coding populating the first slice inside resource
import, use vc4_setup_slices to do it for us.

v2: Rebase on VC4_DEBUG=surf change
