Subject: mesa/clear: remove dead code handling ClearBufferiv(GL_DEPTH)
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=86fd9d6b8e70cdad2755c320e059321fd8c050a1;p=mesa.git

mesa/clear: remove dead code handling ClearBufferiv(GL_DEPTH)

There's a hunk above which sets INVALID_ENUM for GL_DEPTH
unconditionally.
