Subject: broadcom/vc5: Assert that created BOs have offset != 0.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f08f477a93e783361d2942133da18504c2851469;p=mesa.git

broadcom/vc5: Assert that created BOs have offset != 0.

The kernel shouldn't return a bo at NULL, and the HW special-cases NULL
address values for things like OQs.
