Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull first round of SCSI updates from James Bottomley: "This is the usual grab bag of driver updates (hpsa, storvsc, mp2sas, megaraid_sas, ses) plus an assortment of minor updates. There's also an update to ufs which adds new phy drivers and finally a new logging infrastructure for SCSI" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (114 commits) scsi_logging: return void for dev_printk() functions scsi: print single-character strings with seq_putc scsi: merge consecutive seq_puts calls scsi: replace seq_printf with seq_puts aha152x: replace seq_printf with seq_puts advansys: replace seq_printf with seq_puts scsi: remove SPRINTF macro sg: remove an unused variable hpsa: Use local workqueues instead of system workqueues hpsa: add in P840ar controller model name hpsa: add in gen9 controller model names hpsa: detect and report failures changing controller transport modes hpsa: shorten the wait for the CISS doorbell mode change ack hpsa: refactor duplicated scan completion code into a new routine hpsa: move SG descriptor set-up out of hpsa_scatter_gather() hpsa: do not use function pointers in fast path command submission hpsa: print CDBs instead of kernel virtual addresses for uncommon errors hpsa: do not use a void pointer for scsi_cmd field of struct CommandList hpsa: return failed from device reset/abort handlers hpsa: check for ctlr lockup after command allocation in main io path ...
