Merge tag 'omap-for-v4.3/fixes-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Two omap regression fixes:

- Fix omap3 MUSB with DMA caused by driver core changes

- Fix LCD DMA interrupt number for omap1 that did not
  get changed for sparse IRQ changes

* tag 'omap-for-v4.3/fixes-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap
