Hi all, After merging the drm-misc tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/gpu/drm/bridge/analogix/analogix-anx6345.c: In function 'anx6345_i2c_probe': drivers/gpu/drm/bridge/analogix/analogix-anx6345.c:738:30: error: implicit declaration of function 'i2c_new_dummy' [-Werror=implicit-function-declaration] 738 | anx6345->i2c_clients[i] = i2c_new_dummy(client->adapter, | ^~~~~~~~~~~~~ drivers/gpu/drm/bridge/analogix/analogix-anx6345.c:738:28: warning: assignment to 'struct i2c_client *' from 'int' makes pointer from integer without a cast [-Wint-conversion] 738 | anx6345->i2c_clients[i] = i2c_new_dummy(client->adapter, | ^ Caused by commit 6aa192698089 ("drm/bridge: Add Analogix anx6345 support") interacting with commit 2c2f00ab1641 ("i2c: remove i2c_new_dummy() API") From Linus' tree.
