Subject: mesa: fix typo and add assert() to _mesa_attach_renderbuffer_without_ref()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8ffd54fef838784ef4388d48843cddf55246e529;p=mesa.git

mesa: fix typo and add assert() to _mesa_attach_renderbuffer_without_ref()

This function should only be used with a "freshly created" renderbuffer
so assert RefCount is 1.
