Subject: [GIT PULL] ACPI fixes for v3.10-rc7

Hi Linus,

Please pull from the git repository at

  git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git acpi-3.10-rc7

to receive ACPI fixes for v3.10-rc7 with top-most commit

  ACPI / LPSS: Power up LPSS devices during enumeration

on top of commit 7d132055814ef17a6c7b69f342244c410a5e000f

  Linux 3.10-rc6

One of them fixes a regression introduced on some systems by a recent revert
of an ACPI PM change, two of them fix obvious bugs overlooked in 3.9, and
one fixes a problem reported against the mainline just a couple of days
ago, although the fix itself has been in linux-next since 3.10-rc3.

Specifics:

- Fix for a regression causing a failure to turn on some devices on
  some systems during initialization introduced by a recent revert of
  an ACPI PM change that broke something else.  Fortunately, we know
  exactly what devices are affected, so we can add a fix just for
  them leaving everyone else alone.

- ACPI power resources initialization fix preventing a NULL pointer
  from being dereferenced in the acpi_add_power_resource() error code
  path.

- ACPI dock station driver fix that adds missing locking to
  write_undock().

- ACPI resources allocation fix changing the scope of an old
  workaround so that it doesn't affect systems that aren't actually
  buggy.  This was reported a couple of days ago to fix DMA problems
  on some new platforms so we need it in -stable.  From Mika Westerberg.

Thanks!
