Subject: virtual irq isssue - regmap_irq

Hi,

In regmap_irq if irq_base is unknown then regmap creates virq starting from 0
and it seems that in kernel 3.8 virq 0 usage is not permitted, since during irq
registration kernel throws a message "error: irq_desc already associated".

I'm not sure if this requires fix in regmap_irq or kernel, can you please
comment on this?

Thanks,
Ashish
