The dev_id used in 'request_irq()' and 'free_irq()' should match.
So use 'host' in both cases.

This is itself wrong. cumanascsi_2_intr() requires "info" as the devid.
Either cumanascsi_2_intr() needs changing to use shost_priv(host) along
with this change, or free_irq() needs changing to use "info".

My bad.

I've only looked at the difference of the dev_id for the 2 functions, not at the usage of it with the function registered by 'request_irq'. This one is obviously correct, or the driver would have some problems somewhere.
I don't know why have chosen to change request_irq and not free_irq.

So obvious. I'm a little embarrassed and will send a v2.

Thx for the quick reply and review.


All the 3 patches being in "/drivers/scsi/arm/", do you prefer only 1 patch for the 3, or separated as I've done so far?

Likely the same for the other patches, I haven't looked.
