Many thanks for trying to assist me with my problem. To recap,
yeah, no problem ;-)
I'm seeing the keypad lock-up on my N810 using this driver,
when I type quickly.
I tried your patch, and it doesn't fix the issue. However, I've
read the datasheet for the lm8323 and it looks to me like the
interrupt should be level rather than edge triggered.
The following additional patch makes things work for me. I
couldn't tell you if it's the correct thing to do but I can no
longer cause the keypad to lock-up by typing too fast.
good good. Looks like IRQF_ONESHOT is what did the trick.
Did you check if IRQF_ONESHOT alone was enough ?
I tried that first, but it didn't fix it, although it makes it a
little bit harder to trigger. I've just tried again to be sure,
but I got a lock-up quite easily.
Regards,
Leigh.
