Subject: st/omx: Avoid segfault in deconstructor if constructor fails
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=56fc2986d554b93d16fa1151765a9987bc42e4da;p=mesa.git

st/omx: Avoid segfault in deconstructor if constructor fails

If the constructor fails before the LIST_INIT calls the pointers
will be null and the deconstructor will segfault.
