[Mesa-dev] [PATCH 1/4] dri_util: Use calloc to allocate __DRIcontext

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

The __DRIcontext contains some pointers, and some drivers check for them to be
NULL in some failure paths.  Instead of sprinkling NULL assignments across the
various drivers, just zero out the whole thing.

NOTE: This is a candidate for the 9.0 branch.
