AFAIK, it is not a problem.
BTW, what irq line are you requesting for? If this irq line is shared
with some other device, then please add a statement in your interrupt
handler checking wether this interrupt is for your device. You can
check this using the device id.
Hope this helps,
Thanks,
Sumit

Hi all,
I'm developing device driver which handles IR interrupt.
I started it with well-operating qtronix 990p keyboard driver source code
that is built static in the kernel.
I said N for the device in kernel configuation, and modified the source code
in order to make it insmod-able.
and i placed request_irq and some other initializations in the
module_init();
and then i modified the handler to do printk("interrupt...\n"); only.
I compiled and insmoded the module (i checked that it was in
/proc/interrupts).
When I pressed the keyboard the answer was,
interrupt...
interrupt...
interrupt...
...(forever, sometimes hangs in a few seconds of scrolling down,
either way i have to reset the board.)
while it is supposed to be only one "interrupt..."
Is it illegal to place request_irq in the init_module?
Please help.
Thanks in advance.
Theo.
