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.
