Subject: intel: Mark the FBO as incomplete if there's no intel_renderbuffer for it.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8bba183b9eeb162661a287bf2e118c6dd419dd24;p=mesa.git

intel: Mark the FBO as incomplete if there's no intel_renderbuffer for it.

This happens to rendering with textures with a border, which had resulted
in a segfault on dereferencing the irb.
