From 01c83795d50ccdb441f60e89ff50767cb2f6045a Mon Sep 17 00:00:00 2001 From: Felix Gu Date: Sat, 21 Mar 2026 03:12:11 +0800 Subject: [PATCH] drm/bridge: th1520-dw-hdmi: Fix remove() callback This driver stores struct th1520_hdmi * in platform drvdata, but th1520_dw_hdmi_remove() was reading it back as struct dw_hdmi * and passing it to dw_hdmi_remove(), so teardown runs on the wrong pointer. Retrieve struct th1520_hdmi * from platform drvdata and pass hdmi->dw_hdmi to dw_hdmi_remove().
