Adding Wei who added interrupt support to the lm90 driver, and moving

Thanks for the speedy response and list correction.

Just FYI, the Tegra114 Dalmore board here reports an unhandled IRQ about
two minutes after boot:
[ 120.950839] irq 308: nobody cared (try booting with the "irqpoll" option)

[ 121.019825] handlers:

This is on next-20131218.
Which temperature chip is the Tegra114 Dalmore board using?
It's an NCT72.
Is the interrupt shared with something else?
Doesn't look like it. From /proc/interrupts:
308: 74181 0 0 0 GPIO 116 lm90
That's from shortly after boot. From successive 'cat's of
/proc/interrupts, I see that the interrupt count is increasing very
quickly. So something is definitely not right.
Is there any monitoring script, application or daemon polling for
temperatures on this system?
This is a totally quiet system, booted with 'init=/bin/bash' on the kernel
command line - nothing else running at all.
regards
- Paul
