From: Ville Syrjälä Date: Thu, 1 Jun 2017 14:36:19 +0000 (+0300) Subject: drm/i915: Remove pipe A quirk remnants X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e56134bc79569d5aa912c957f2fd4d92ea21fcc8;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Remove pipe A quirk remnants With 830 the only thing needing pipe quirks, we can just drop the quirk defines and replace the checks with IS_I830() checks.
