Subject: [PATCH 0/2] Clause-22/Clause-45 MDIO regmap support fixups

A proposed patch to make C22 access more strict [1], was posted in reply to an
RFC series which also added C45 register access [2]. It appears that as a
result, the original RFC patches got merged instead.

Since there are currently no (planned) C45 regmap users, this patch is
reverted. C22 access functions are corrected to return -ENXIO, instead of
silently ignoring any invalid high bits in the register offset.

[1] Proposed C22 patch:
https://lore.kernel.org/lkml/20210605083116.12786-1-sander@svanheule.net/

[2] RFC series:
https://lore.kernel.org/lkml/cover.1622743333.git.sander@svanheule.net/

Sander Vanheule (2):
  Revert "regmap: mdio: Add clause-45 support"
  regmap: mdio: Reject invalid clause-22 addresses
