Hi,

gpio-leds fails to probe on OCTEON with v4.8-rc3 and when using
arch/mips/boot/dts/cavium-octeon/dlink_dsr-1000n.dts. Leds still
worked with v4.7.

I bisected this to:

	of/irq: Mark initialised interrupt controllers as populated

I have no idea how this is related to gpio-leds, except that on OCTEON
DTBs the gpio node is also interrupt controller...

Hey Aaro.

It is actually two patches that cause the breakage. The other is:

    commit e55aeb6ba4e8cc3549bff1e75ea1d029324bce21
    of/irq: Mark interrupt controllers as populated before initialisation

I needed to revert both of these in order to get MMC working on our 71xx 
and 78xx boards. For our MMC, I got error messages from the MMC core of 
"Invalid POWER GPIO" until I applied the second patch. I will have a fix 
worthy of upstreaming today which will be posted today.
