Hi Greg,

After merging the driver-core tree, today's linux-next build ()
failed like this on a PowerPC defconfig:

HEAD is now at ceb98e684dec Merge remote-tracking branch 'driver-core/driver-core-next'
  GEN     /home/broonie/next/powerpc_ppc64_defconfig/Makefile
#
# configuration written to .config

/home/broonie/next/next/arch/powerpc/platforms/powernv/opal-elog.c: In function 'elog_ack_store':
/home/broonie/next/next/arch/powerpc/platforms/powernv/opal-elog.c:84:2: error: implicit declaration of function 'sysfs_schedule_callback' [-Werror=implicit-function-declaration]
  sysfs_schedule_callback(&elog_obj->kobj, delay_release_kobj,
  ^
cc1: all warnings being treated as errors
make[3]: *** [arch/powerpc/platforms/powernv/opal-elog.o] Error 1
make[3]: *** Waiting for unfinished jobs....
/home/broonie/next/next/arch/powerpc/platforms/powernv/opal-dump.c: In function 'dump_ack_store':
/home/broonie/next/next/arch/powerpc/platforms/powernv/opal-dump.c:100:2: error: implicit declaration of function 'sysfs_schedule_callback' [-Werror=implicit-function-declaration]
  sysfs_schedule_callback(&dump_obj->kobj, delay_release_kobj,
  ^
cc1: all warnings being treated as errors

due to an interaction between d1ba277e7988908 (sysfs, driver-core: remove unused {sysfs|device}_schedule_callback_owner()) and 774fea1a38c6a5a8 (powerpc/powernv: Read OPAL error log and export it through sysfs) from the PowerPC tree.

I reverted 774fea1a38c6a5a8 for today.
