four small fixes, three in drivers and one in the FC transport class to add idempotence to state setting. The patch is available here: git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes The short changelog is: Avri Altman (1): scsi: ufs: Use pre-calculated offsets in ufshcd_init_lrb() Benjamin Marzinski (1): scsi: scsi_transport_fc: Allow setting rport state to current state Daniel Palmer (1): scsi: wd33c93: Don't use stale scsi_pointer value Martin Wilck (1): scsi: fnic: Move flush_work initialization out of if block And the diffstat: drivers/scsi/fnic/fnic_main.c | 2 +- drivers/scsi/scsi_transport_fc.c | 4 ++-- drivers/scsi/wd33c93.c | 2 +- drivers/ufs/core/ufshcd.c | 5 ++--- 4 files changed, 6 insertions(+), 7 deletions(-) With full diff below.
