linux-next: build failure after merge of the driver-core tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
