From fb721b2c35b1829b8ecf62e3adb41cf30260316a Mon Sep 17 00:00:00 2001 From: Louis Chauvet Date: Tue, 29 Apr 2025 10:36:23 +0200 Subject: [PATCH] drm: writeback: Fix drm_writeback_connector_cleanup signature MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The drm_writeback_connector_cleanup have the signature: static void drm_writeback_connector_cleanup( struct drm_device *dev, struct drm_writeback_connector *wb_connector) But it is stored and used as a drmres_release_t typedef void (*drmres_release_t)(struct drm_device *dev, void *res); While the current code is valid and does not produce any warning, the CFI runtime check (CONFIG_CFI_CLANG) can fail because the function signature is not the same as drmres_release_t. In order to fix this, change the function signature to match what is expected by drmres_release_t.
