From: Imre Deak Date: Mon, 5 Aug 2024 15:07:53 +0000 (+0300) Subject: drm/i915: Replace to_bpp_frac() with fxp_q4_to_frac() X-Git-Tag: v6.12-rc1~126^2~22^2~13 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e60244554ca98e87ef731739f608eac54e478e9a;p=thirdparty%2Flinux.git drm/i915: Replace to_bpp_frac() with fxp_q4_to_frac() Replace the to_bpp_frac() helper defined by the driver with the equivalent fxp_q4_to_frac() helper defined by DRM core. v2: Rebase on the s/drm_x16/fxp_q4 change.
