Hi all, After merging the drm-misc tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:4031:18: error: initialization of 'int (*)(struct drm_connector *, struct drm_atomic_state *)' from incompatible pointer type 'int (*)(struct drm_connector *, struct drm_connector_state *)' [-Werror=incompatible-pointer-types] .atomic_check = amdgpu_dm_connector_atomic_check, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:4031:18: note: (near initialization for 'amdgpu_dm_connector_helper_funcs.atomic_check') Caused by commit 6f3b62781bbd ("drm: Convert connector_helper_funcs->atomic_check to accept drm_atomic_state") interacting with commit 88694af9e4d1 ("drm/amd/display: Expose HDR output metadata for supported connectors") from the drm tree. I added the following merge fix patch: From: Stephen Rothwell Date: Fri, 14 Jun 2019 14:27:12 +1000 Subject: [PATCH] fixup for "drm: Convert connector_helper_funcs->atomic_check to accept drm_atomic_state" Signed-off-by: Stephen Rothwell --- drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c index 413bf22e9585..b3a083c9a11c 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c @@ -3976,9 +3976,10 @@ is_hdr_metadata_different(const struct drm_connector_state *old_state, static int amdgpu_dm_connector_atomic_check(struct drm_connector *conn, - struct drm_connector_state *new_con_state) + struct drm_atomic_state *state) { - struct drm_atomic_state *state = new_con_state->state; + struct drm_connector_state *new_con_state = + drm_atomic_get_new_connector_state(state, conn); struct drm_connector_state *old_con_state = drm_atomic_get_old_connector_state(state, conn); struct drm_crtc *crtc = new_con_state->crtc; -- 2.20.1 -- Cheers, Stephen Rothwell
