Subject: i965/meta: initialize values to avoid random behaviour on error path
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ec5f7fc7bd1104700738f27f0e79269fe3ab4072;p=mesa.git

i965/meta: initialize values to avoid random behaviour on error path

if brw_meta_stencil_blit() errored at wrong place 'target' would
be uninitialized and cause random behaviour on leaving the funtion.
