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: > There is an immutable tag that can be merged into your tree to > resolve the conflict before you send your changes to Linux at > > https://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git i2c/make_remove_callback_void-immutable I have applied the following merge fix patch for today.
