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.

Hups, seems I missed your EMail :-(

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

Good :-)

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.

Hmm.. I did not see this on the enbw_cmc board. Maybe I can try it
on the TMDXEXP1808L board, but I must admit, that I am currently lacking
time, because of an accident ...

bye,
Heiko
