Hello,
I tested gpio-rcar driver at Linux-upstream-v3.16-rc5 on Lager.
When I tried to unbind and then rebind the device, error messages occur.
Then
gpio-rcar did not work and interrupt number did not count up any more.
The error messages is showed as below:
"irq 0, desc: ee005040, depth: 1, cou0
->handle_irq(): c005eea0, handle_bad_irq+0x0/0x21c
->irq_data.chip(): c05de7f8, 0xc05de7f8
->action(): (null)
IRQ_NOPROBE set
IRQ_NOREQUEST set
irq 0, desc: ee005040, depth: 1, count: 0, unhandled: 0
->handle_irq(): c005eea0, handle_bad_irq+0x0/0x21c
->irq_data.chip(): c05de7f8, 0xc05de7f8
->action(): (null)
IRQ_NOPROBE set
IRQ_NOREQUEST set"
Please see it and fix this bug.
Best regards,
JINSO/Cao Minh Hiep.
