I have gone through the "Linux generic IRQ handling" page [1] but I
could not find a definitive answer to my question. So hopefully you can
clarify it for me.
I was wondering whether a disable_irq() must be followed by
enable_irq(), leaving the nested disable out of this, or could one call
free_irq() for a disabled irq.
Regards,
Arend
