Subject: llvmpipe: (trivial) initialize src1_alpha var to NULL
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=64d3ae09b72ee1052560c1704d628b433140e895;p=mesa.git

llvmpipe: (trivial) initialize src1_alpha var to NULL

The blend code would do a conditional assignment based on it, causing valgrind
to complain. Since that variable was actually unused in this case, this
doesn't fix anything but the warning.
