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.
# cat /proc/interrupts

61: 270 cp_intc serial
93: 0 cp_intc edma
94: 0 cp_intc edma_error
Err: 32
The interrupt number 0 shows up which seems to be causing these warnings.
I also had to select IRQ_DOMAIN for CP_INTC in
arch/arm/mach-davinci/Kconfig to make the kernel builds after applying
this patch.
Thanks,
Sekhar
