Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

From Tony Lindgren:

Note that this also contains a set of fixes that are not regressions
or oopses to properly deal with the smsc911x regulator issue.

Basically the regulators must be per board file as the regulators
can also come from drivers, such as twl4030. So it's best to dumb
down gpmc-smsc911x.c to not even care about the regulators.

* 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP: fix section mismatches in usb-host.c
  ARM: OMAP2+: Fix omap2+ build error
  ARM: OMAP2+: smsc911x: Add fixed board regulators
  ARM: OMAP2+: smsc911x: Remove regulator support from gmpc-smsc911x
  ARM: OMAP2+: smsc911x: Remove unused rate calculation
  ARM: OMAP2+ smsc911x: Fix possible stale smsc911x flags
  ARM: OMAP2+: smsc911x: Remove odd gpmc_cfg/board_data redirection
  ARM: OMAP3+: fix oops triggered in omap_prcm_register_chain_handler(v1)
  ARM: OMAP2+: OPP: allow OPP enumeration to continue if device is not present
  arm: omap3: pm34xx.c: Replace printk() with appropriate pr_*()
  arm: omap3: pm34xx.c: Fix omap3_pm_init() error out paths
  ARM: OMAP4: Workaround the OCP synchronisation issue with 32K synctimer.
  ARM: OMAP4: prm: fix interrupt register offsets
  ARM: OMAP: hwmod: Use sysc_fields->srst_shift and get rid of hardcoded SYSC_TYPE2_SOFTRESET_MASK
