Hi all,

After merging the hwmon-staging tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/hwmon/emc2305.c:615:21: error: initialization of 'void (*)(struct i2c_client *)' from incompatible pointer type 'int (*)(struct i2c_client *)' [-Werror=incompatible-pointer-types]
  615 |         .remove   = emc2305_remove,
      |                     ^~~~~~~~~~~~~~
drivers/hwmon/emc2305.c:615:21: note: (near initialization for 'emc2305_driver.remove')

Caused by commit

  324745b64626 ("hwmon: (emc2305) add support for EMC2301/2/3/5 RPM-based PWM Fan Speed Controller.")

interacting with commit

  ed5c2f5fd10d ("i2c: Make remove callback return void")

from the i2c tree.

From Uwe:

I have applied the following merge fix patch for today.
