Subject: [PATCH v3 0/4] Re-use device management code fragments

v2->v3:
 - 2/4 - Clarify commit log (Bean)
 - 4/4 - pass cmd_type to ufshcd_prepare_req_desc_hdr (Bean)

v1->v2:
 - Attend Bart's comments


Device management commands are constructed for query commands that are
being issued by the driver, but also for raw device management commands
originated by the bsg module, and recently, by the advanced rpmb
handler. Thus, the same code fragments, e.g. locking, composing the
command, composing the upiu etc., appear over and over. Remove those
duplications.  Theoretically, there should be no functional change.

Avri Altman (4):
  scsi: ufs: Re-use device management locking code
  scsi: ufs: Re-use exec_dev_cmd
  scsi: ufs: Re-use compose_dev_cmd
  scsi: ufs: Re-use compose_devman_upiu
