Merge tag 'omap-for-v3.9-rc3/fixes-signed' of... 

Merge tag 'omap-for-v3.9-rc3/fixes-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

From Tony Lindgren <tony@atomide.com>:

A clock regression fix that happened with the common clock
conversion, and few USB regression fixes.

* tag 'omap-for-v3.9-rc3/fixes-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap

:
  ARM: OMAP: clocks: Delay clk inits atleast until slab is initialized
  ARM: OMAP4: PM: fix PM regression introduced by recent clock cleanup
  ARM: OMAP3: hwmod data: keep MIDLEMODE in force-standby for musb
  ARM: OMAP4: clock data: lock USB DPLL on boot
  ARM: OMAP1: fix USB host on 1710
