[PATCH] wrong thing iounmapped (qla3xxx)

ql3xxx_probe() does ioremap and stores result in ->mem_map_registers.
On failure exit it does iounmap() of the same thing.

OTOH, ql3xxx_remove() does iounmap() of ->mmap_virt_base which is
 (a) never assigned and
 (b) never used other than in that iounmap() call.
