From: Luca Coelho Date: Thu, 5 Mar 2026 09:59:05 +0000 (+0200) Subject: drm/i915/display: convert audio workaround to new framework X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=57288a60ef387934fc4842ccaa8ad9a6176ed24c;p=thirdparty%2Flinux.git drm/i915/display: convert audio workaround to new framework Convert the low-hanging fruits of workaround checks to the workaround framework. Instead of having display structure checks for the workarounds all over, concentrate the checks in intel_display_wa.c.
