When using mcp23s08 module with gpio-keys, often (50% of boots)

Seems that irqs must be setup before devm_gpiochip_add_data().

Patch applied, albeit for devel.
Should it be tagged for stable or go into fixes?
I'm no expert on this one, but looking at other drivers they're using a mixture of ordering
for irq setup and devm_gpiochip_add_data() calls.
But should probably go into stable if it is the fix.
