[PATCH v2 0/4] ufs: Let the SCSI core allocate per-command UFS data

[Bart Van Assche <bvanassche@xxxxxxx>]

Hi Martin,

This patch series lets the SCSI core allocate per-command UFS data and hence
simplifies and micro-optimizes the UFS driver. Please consider this patch
series for the v5.6 kernel.

Thanks,

Bart.

Changes compared to v1:
- Restored an accidentally removed ufshcd_release() call in an error path in
  ufshcd_queuecommand().
- Check whether ufshcd_tag_to_lrb() returns a non-NULL pointer in
  ufshcd_eh_device_reset_handler().

Bart Van Assche (4):
  Introduce {init,exit}_cmd_priv()
  ufs: Introduce ufshcd_init_lrb()
  ufs: Simplify two tests
  ufs: Let the SCSI core allocate per-command UFS data
