Subject: vc4: Fix another space allocation mistake.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cb88d2cfcb1f4444d1ec351277e8b662cda81a5e;p=mesa.git

vc4: Fix another space allocation mistake.

We're over-allocating our BCL in vc4_draw.c, so this never mattered.
However, new RCL-only blit support might end up here without having set up
any BCL contents.
