Merge tag 'mips_fixes_5.1_2' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux

Pull MIPS fixes from Paul Burton:
 "A few minor MIPS fixes:

   - Provide struct pt_regs * from get_irq_regs() to kgdb_nmicallback()
     when handling an IPI triggered by kgdb_roundup_cpus(), matching the
     behavior of other architectures & resolving kgdb issues for SMP
     systems.

   - Defer a pointer dereference until after a NULL check in the
     irq_shutdown callback for SGI IP27 HUB interrupts.

   - A defconfig update for the MSCC Ocelot to enable some necessary
     drivers"

* tag 'mips_fixes_5.1_2' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux:
  MIPS: generic: Add switchdev, pinctrl and fit to ocelot_defconfig
  MIPS: SGI-IP27: Fix use of unchecked pointer in shutdown_bridge_irq
  MIPS: KGDB: fix kgdb support for SMP platforms.
