The module catches IRQ5, then raises signal to user space application after checking corresponding status register. It also provides ioctl method which response to CPLD to notify LED on/off .

Thanks for the patch, but can you resend it with a Signed-off-by: line,
as described by Documentation/SubmittingPatches?  We need that before we
can take anything.

Also, you should run the code through scripts/checkpatch.pl and fix up
the errors it finds.  There are still a number of basic coding style
fixes that need to be done.

And finally, this code really should tie the LED interaction into the
LED kernel subsystem, so that you do not need a custom userspace program
to handle ioctls just for LED control.  Do you need help in making those
changes?

thanks,
