Please consider these UFS driver kernel patches for kernel v5.17. Thanks, Bart. Changes compared to v1: - Introduced the symbolic constant UFSHCD_NUM_RESERVED. - Changed the behavior of the patch that removes the clock scaling lock from ufshcd_queuecommand() such that it again waits until all pending commands have finished before changing the clock frequency. - Split the patch that optimizes ufshcd_queuecommand(). - Added patches that introduce support for internal command management in the SCSI core. - Introduced a new function ufshcd_release_scsi_cmd().
