Subject: [PATCH v2 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.

Access functions are corrected to return -ENXIO, instead of silently ignoring
any invalid high bits in the register offset.
Additionally, a warning about a discarded const qualifier is fixed.

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

[2] RFC series:

Changes since v1:
Link: https://lore.kernel.org/lkml/cover.1623238313.git.sander@svanheule.net/
- Keep C45 access code, but apply fix for discarded pointer constness
- Return -ENXIO for invalid C45 access too, as done for invalid C22 access

Sander Vanheule (2):
  regmap: mdio: Fix regmap_bus pointer constness
  regmap: mdio: Reject invalid addresses
