Subject: st/gbm: don't segfault if the fail to create the screen
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e3a3dbe9407bdbf9693349900936d5349cb8bb75;p=mesa.git

st/gbm: don't segfault if the fail to create the screen

Whenever dd_create_screen/pipe_loader_* fails, gdrm->dev may be NULL.
Thus peeking inside the struct will lead to a crash.
