From 603a945e55bddc9265bb40d27fd1de3ab3d0316b Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 4 Mar 2021 19:04:21 +0200 Subject: [PATCH] drm/i915: Fix DSI TE max_vblank_count handling MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit commit 33267703df15 ("drm/i915/dsi: Enable software vblank counter") claims to get the mode_flags from the crtc_state, but in fact does not. Fix it to do it right.
