Subject: i965: Drop intel_check_front_buffer_rendering().
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=feb3d8dacd587683ded706049d696d1904cb87cd;p=mesa.git

i965: Drop intel_check_front_buffer_rendering().

This was being applied in a subset of the places that
intel_prepare_render() was called, to set the same flag that
intel_prepare_render() was setting.
