Subject: virtual irq isssue - regmap_irq
Date: Thu, 7 Mar 2013 12:27:52 +0530 [thread overview]
Message-ID: <1362639472.484.22.camel@dhruva> (raw)
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
