Hi.
(I have not been able to find a probable maintainer for this code.)
The follow patch makes drivers/scsi/qlogicfas.c use the return code
from request_region instead of a call to check_region. It also
adds a missing free_irq on an error path and makes us check the
return from scsi_register.
It applies cleanly against ac10 and 241p9.
Comments?
