Great, thanks! Fred spotted a problem with irq_free_descs() not doing
kobject_put() anymore and this is a problem for sa1111.c and the likes
and I will go though these places anyway.
So there are callers out there which don't care about mapping the
interrupt. Wouldn't it be easier to leave alone the kobject from the irq
descriptor (my understanding is that it's there to handle the sysfs
representation) and add a simple kref counter, just to handle the
mapping part?
