Subject[GIT PULL] More power management updates for 3.4
Hi Linus,

I prepared this on Friday with the hope to send the pull request before the end
of the merge window, but then I had to go to San Francisco (for the LFCS) and
missed the opportunity. That said, this includes fixes mostly (and -stable
ones for that matter), so I think it's appropriate for the -rc1 time frame too.

Please pull additional power management updates for 3.4 since commit

Merge tag 'common-clk-api' of git://

with top-most commit c4772d192c70b61d52262b0db76f7abd8aeb51c6:

PM / QoS: add pm_qos_update_request_timeout() API

from the git repository at:

git:// pm-for-3.4-part-2

This mostly consists of fixes and changes requisite for those fixes, with the
exception of the last commit, which is a new feature. However, that new
feature is reasonably isolated and very unlikely to cause any regressions to
happen, although it is necessary for some future changes in the works now.
Included are:

* Patch series that hopefully fixes races between the freezer and request_firmware()
and request_firmware_nowait() for good, with two cleanups from Stephen Boyd on top.

* Runtime PM fix from Alan Stern preventing tasks from getting stuck indefinitely
in the runtime PM wait queue.

* Device PM QoS update from MyungJoo Ham introducing a new variant of
pm_qos_update_request() allowing the callers to specify a timeout.
