Subject[PATCH] make drivers/scsi/qlogicfc.c check_region -> request_region + cleanup (241p9)
Hi.

(I am guessing you as the maintainer of this code. If you are not,
I apologize for your inconvenience.)

The following patch makes drivers/scsi/qlogicfc.c check the
return code of scsi_register, adds a missing pci64_free_consistent on
an error path and makes it use request_region exclusively.

It applies cleanly against ac10 and 241p9.

Comments?
