Subject: panfrost: Don't zero staging buffer for tiling
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=48cc608859cceb523da1a5e74c0e4aad91f3984c;p=mesa.git

panfrost: Don't zero staging buffer for tiling

It's a little less safe but the memset does take time during
initialization. v3d doesn't either, so I think  it's ok.
