Building hbm.o for v3.13.2 triggers a GCC warning:
drivers/misc/mei/hbm.c: In function 'mei_hbm_dispatch':
drivers/misc/mei/hbm.c:596:3: warning: 'return' with a value, in function returning void [enabled by default]
return 0;
^
GCC is correct, obviously. So let's return void instead of zero here.

Pull driver core patches from Greg KH:
"Here's the big driver core pull request for 3.12-rc1.
Lots of tiny changes here fixing up the way sysfs attributes are
created, to try to make drivers simpler, and fix a whole class race
conditions with creations of device attributes after the device was
announced to userspace.
All the various pieces are acked by the different subsystem
maintainers"

The dev_attrs field of struct bus_type is going away soon, dev_groups
should be used instead. This converts the MEI bus code to use
the correct field.

Both H_IS and H_IE needs to be set to receive H_RDY
interrupt
1. Assert H_IS to clear the interrupts during hw reset
and use mei_me_reg_write instead of mei_hcsr_set as the later
strips down the H_IS
2. fix interrupt disablement embarrassing typo
hcsr |= ~H_IE -> hcsr &= ~H_IE;
this will remove the unwanted interrupt on power down
3. remove useless debug print outs

Flushing pending work items before resetting the device makes more
sense than doing so afterwards. Some of them, like e.g. the NFC
initialization one, find themselves with client IDs changed after
the reset, eventually leading to trigger a client.c:mei_me_cl_by_id()
warning after a few modprobe/rmmod cycles.

in client properites the read can be much longer delivered consequiting chunks.
We use krealloc to enlarge the buffer when needed.
