On AM18x EVM, with this patch applied and CONFIG_KEYBOARD_GPIO_POLLED=y,
I get warnings of type:

irq 0, desc: c0372950, depth: 1, count: 0, unhandled: 0

->handle_irq():  c00552f8, handle_bad_irq+0x0/0x23c

->irq_data.chip(): c03794e8, 0xc03794e8

->action():   (null)

   IRQ_NOPROBE set

 IRQ_NOREQUEST set


They do not come when CONFIG_KEYBOARD_GPIO_POLLED=n. I am yet to debug
this, but wanted to point out now in case there is anything obvious.

I debugged this a bit more and the good news for you is that spurious
IRQ messages have got nothing to do with your patch. Looks like the
spurious interrupts on interrupt line 0 were always there - just that
they were getting silently ignored earlier. I am still debugging what is
causing these spurious interrupts.

Thanks,
Sekhar
