Hi Martin,

This patch series includes the following changes:
- Fix a deadlock in the UFS error handler.
- Add polling support in the UFS driver.
- Several smaller fixes for the UFS driver.

Please consider these UFS driver kernel patches for kernel v5.17.

Thanks,

Bart.

Changes compared to v2:
- Dropped SCSI core patches that add support for internal commands.
- Reworked patch "Fix a deadlock in the error handler" such that it uses a
  reserved tag as proposed by Adrian.
- Split patch "ufs: Introduce ufshcd_release_scsi_cmd()" into two patches.

Changes compared to v1:
- Add internal command support to the SCSI core.
- Reworked patch "ufs: Optimize the command queueing code".
