Subject: [SCSI] bsg: replace kobject_get with blk_get_queue
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c3ff1b90d8924dd1c55c3b56a79bfc563ace4a42;p=mv-sheeva.git

[SCSI] bsg: replace kobject_get with blk_get_queue

Both takes a ref to a queue. But blk_get_queue checks QUEUE_FLAG_DEAD
and is more appropriate interface here.
