Subject: mesa: Fix VAO buffer object tracking.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2f9eb0aad5a0d2177b52a22d012fd53438edf9fe;p=mesa.git

mesa: Fix VAO buffer object tracking.

When changing the attribute binding in the VAO we also need to
account for getting rid of non vbo bits from VertexAttribBufferMask.
