Subject: [PATCH v4 0/3] scsi: ufs: Add crypto_keyslot_remap support

Hello Eric,

Sorry for late due to other affairs.

Readjuest the patchset adds support for platform-specific crypto keyslot
remapping in the exynos UFS host driver.

The 1st patch raise a new variant op:
  ufs_hba_variant_ops::crypto_keyslot_remap
which allows platforms to adjust the keyslot index at io request period.

The 2nd patch adds a real, upstream user in ufs-exynos.c that supports
remapping via device tree. This makes the hook justifiable for mainline
inclusion.

The 3rd patch adds DT binding description for the new property
'ufs-keyslot-offset'.
