Merge tag 'omap-for-v3.13/intc-ldp-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

From Tony Lindgren:
Fix a regression for wrong interrupt numbers for some devices after
the sparse IRQ conversion, fix DRA7 console output for earlyprintk,
and fix the LDP LCD backlight when DSS is built into the kernel and
not as a loadable module.

* tag 'omap-for-v3.13/intc-ldp-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP2+: Fix LCD panel backlight regression for LDP legacy booting
  ARM: OMAP2+: hwmod_data: fix missing OMAP_INTC_START in irq data
  ARM: DRA7: hwmod: Fix boot crash with DEBUG_LL
  + v3.13-rc5
