Subject: [PATCH v1 0/4] Add ioctl and debug utilities to UFS driver

This patch series introduces in the first change a new UFS ioctl,
allowing user-space to send UFS queries and retrieve information from them.
In addition, the other three patches add utilities to support debugging
efforts and supply information that will help analysis of issue:
UFS trace events, dump host controller registers and requests descriptors
on failures, several statistics.

Dolev Raviv (1):
  scsi: ufs: add ioctl interface for query request

Gilad Broner (1):
  scsi: ufs: add trace events and dump prints for debug

Lee Susman (1):
  scsi: ufs: add debugfs for ufs

Sujit Reddy Thumma (1):
  scsi: ufs: inject errors to verify error handling
