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"

MEI: convert bus code to use dev_groups

2013-08-23T21:38:12+00:00

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.

mei: me: fix hardware reset flow

2013-08-12T22:46:06+00:00

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

mei: don't get stuck in select during reset

2013-07-27T00:54:30+00:00

Clear pending connection after hw reset but before hw start
and wake up the waiting task in poll. Signal POLLERR in select
when device went through reset.

Add wrapper mei_cl_is_connected for checking if
the device and client are connected.

1. use strncmp for comparsion strncpy was used for copying
which may omit the final %NUL terminator
2. id->name is statically defined so we can use sizeof

mei: me: fix waiting for hw ready

2013-07-24T02:31:35+00:00

1. MEI_INTEROP_TIMEOUT is in seconds not in jiffies
so we use mei_secs_to_jiffies macro
While cold boot is fast this is relevant in resume
2. wait_event_interruptible_timeout can return with
-ERESTARTSYS so do not override it with -ETIMEDOUT
3.Adjust error message

mei: don't have to clean the state on power up

When powering up, we don't have to clean up the device state
nothing is connected.

mei: me: fix reset state machine

2013-07-24T02:31:34+00:00

ME HW ready bit is down after hw reset was asserted or on error.
Only on error we need to enter the reset flow, additional reset
need to be prevented when reset was triggered during
initialization , power up/down or a reset is already in progress
