Subject: drm/i915: add HAS_BSD check to i915_getparam
X-Git-Tag: v2.6.35-rc2~56^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e3a815fcd38043b8f1bb526123d8ab6ae01deb77;p=platform%2Fkernel%2Flinux-stable.git

drm/i915: add HAS_BSD check to i915_getparam

This will let userland only try to use the new media decode
functionality when the appropriate kernel is present.
