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 *")
