[Mesa-dev] [PATCH 7/9] i915: Protect macro argument for TEXTURE_SET()

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

TEXTURE_SET() is the only register macro that forgets to wrap the
argument evaluation in parens. Only simple integers are passed to this
macro so there's no bug but sitll it seems prudent to add the
parens.
