Subject: glsl: Return NULL on _slan_gen_asm error path on non-debug builds.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3c90777fd7cce57486dc7d98e676ffe9dede55ae;p=mesa.git

glsl: Return NULL on _slan_gen_asm error path on non-debug builds.

Exit the function early on the error path, instead of continuing, to
prevent a null pointer dereference later on.
