Re: [BISECTED REGRESSION] v4.8-rc: gpio-leds broken on OCTEON

Hi,

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.

The below change works for me...
