Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI fixes from James Bottomley:
"Four small fixes, three in drivers with the core one adding a batch
indicator (for drivers which use it) to the error handler"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: ufs: core: Let the sq_lock protect sq_tail_slot access
scsi: ufs: qcom: Return ufs_qcom_clk_scale_*() errors in ufs_qcom_clk_scale_notify()
scsi: core: Always send batch on reset or error handling command
scsi: bnx2fc: Fix skb double free in bnx2fc_rcv()
