Subject[PATCH v1] scsi: dc395: fix error case unwinding
Date
dc395x_init_one()->adapter_init() might fail. In this case, the acb
is already clean up by adapter_init(), no need to do that in
adapter_uninit(acb) again.

[ 1.252251] dc395x: adapter init failed
[ 1.254900] RIP: 0010:adapter_uninit+0x94/0x170 [dc395x]
[ 1.260307] Call Trace:
[ 1.260442] dc395x_init_one.cold+0x72a/0x9bb [dc395x]
