Subject: mesa: fix using texture id 0 with glTextureStorage*()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=51a7e0d14f1d1e61f407685d43e248d68340fbb4;p=mesa.git

mesa: fix using texture id 0 with glTextureStorage*()

This fixes an assertion in debug build, and probably a crash
in release build.
