Subject: auxiliary/vl/dri: fd management cleanups
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5d294d9fa3dcdf8453d97f35e2c799efa887cbcc;p=mesa.git

auxiliary/vl/dri: fd management cleanups

Analogous to previous commit, minus the extra dup. We are the one
opening the device thus we can directly use the fd.
