Hi all, After merging the driver-core tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/gpu/drm/../../accel/drm_accel.c: In function 'accel_sysfs_init': drivers/gpu/drm/../../accel/drm_accel.c:41:30: error: assignment to 'char * (*)(const struct device *, umode_t *)' {aka 'char * (*)(const struct device *, short unsigned int *)'} from incompatible pointer type 'char * (*)(struct device *, umode_t *)' {aka 'char * (*)(struct device *, short unsigned int *)'} [-Werror=incompatible-pointer-types] 41 | accel_class->devnode = accel_devnode; | ^ Caused by commit ff62b8e6588f ("driver core: make struct class.devnode() take a const *") interacting with commit 8bf4889762a8 ("drivers/accel: define kconfig and register a new major") from the drm tree. I have applied the following merge resolution patch.
