From: Paulo Zanoni Date: Tue, 19 Jan 2016 13:35:55 +0000 (-0200) Subject: drm/i915/fbc: don't store the fb_id on reg_params X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b20d27526cb0e8dd2b7db3b45ec96aecfc02d610;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915/fbc: don't store the fb_id on reg_params We don't actually use fb_id anywhere. We already compare all parameters that matter to the hardware: pixel format, stride, fence_reg and ggtt_offset. The ID shouldn't make a difference. Besides, we already update the FBC data at every modeset/flip, so this can't change behind our backs.
