Hi all, After merging the driver-core tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: arch/powerpc/platforms/ps3/system-bus.c:472:19: error: initialization of 'int (*)(const struct device *, struct kobj_uevent_env *)' from incompatible pointer type 'int (*)(struct device *, struct kobj_uevent_env *)' [-Werror=incompatible-pointer-types] 472 | .uevent = ps3_system_bus_uevent, | ^~~~~~~~~~~~~~~~~~~~~ arch/powerpc/platforms/ps3/system-bus.c:472:19: note: (near initialization for 'ps3_system_bus_type.uevent') arch/powerpc/platforms/pseries/ibmebus.c:436:22: error: initialization of 'int (*)(const struct device *, struct kobj_uevent_env *)' from incompatible pointer type 'int (*)(struct device *, struct kobj_uevent_env *)' [-Werror=incompatible-pointer-types] 436 | .uevent = ibmebus_bus_modalias, | ^~~~~~~~~~~~~~~~~~~~ arch/powerpc/platforms/pseries/ibmebus.c:436:22: note: (near initialization for 'ibmebus_bus_type.uevent') Caused by commit 2a81ada32f0e ("driver core: make struct bus_type.uevent() take a const *") I have applied the following merge fix patch.
