Four small fixes, three in drivers with the core one adding a batch indicator (for drivers which use it) to the error handler. The patch is available here: git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes The short changelog is: Alexander Atanasov (1): scsi: core: Always send batch on reset or error handling command Can Guo (1): scsi: ufs: core: Let the sq_lock protect sq_tail_slot access ChanWoo Lee (1): scsi: ufs: qcom: Return ufs_qcom_clk_scale_*() errors in ufs_qcom_clk_scale_notify() Wei Yongjun (1): scsi: bnx2fc: Fix skb double free in bnx2fc_rcv() And the diffstat: drivers/scsi/bnx2fc/bnx2fc_fcoe.c | 9 +++------ drivers/scsi/scsi_error.c | 2 ++ drivers/ufs/core/ufshcd.c | 3 ++- drivers/ufs/host/ufs-qcom.c | 6 ++++-- 4 files changed, 11 insertions(+), 9 deletions(-) With full diff below.
