drm/i915: Introduce INTEL_GEN_MASK
Split INTEL_GEN_MASK out of IS_GEN macro, and make it usable within static declarations (unlike compound statements). v2: - s/combound/compound/ (Tvrtko) - Fix whitespace (yes, we need automatic checkpatch.pl) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170913115255.13851-1-joonas.lahtinen@linux.intel.com
