Subject: panfrost/decode: Clip mali_compute_fbd at 64-bytes
X-Git-Tag: upstream/19.3.0~5273
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ae2bfab7b73a1cc2e75f3cbe9a1407e78a23de90;p=platform%2Fupstream%2Fmesa.git

panfrost/decode: Clip mali_compute_fbd at 64-bytes

Looking at internal evidence (later fields including a literal other
compute job inception-style, seeming memory corruption, no clear
function, and the field after this being a pointer to *itself*), it
looks like this is really a much smaller descriptor.
