From 1e9974c7583456ca0bb9ccbf028c86154560f819 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Thu, 7 Dec 2023 16:49:41 +0100 Subject: [PATCH] drm/vc4: hdmi: Create destroy state implementation Even though we were rolling our own custom state for the vc4 HDMI controller driver, we were still using the generic helper to destroy that state. It was mostly working since the underlying state is the first member of our state so the pointers are probably equal in all relevant cases, but it's still fragile so let's fix this properly.
