Subject: [PATCH v2 0/8] regulator: Use container_of_const() when all types
 are const

Changes in v2:
- Rebase on regulator/for-next, which does not have pf1550-regulator.c
  so drop this part.
- Link to v1: https://patch.msgid.link/20251126-container-of-const-regulator-v1-0-eeec378144d4@oss.qualcomm.com

Use container_of_const(), which is preferred over container_of(), when
the argument 'ptr' and returned pointer are already const, for better
code safety and readability.

Some drivers already have const everywhere, so container_of_const can be
directly used. In few other drivers, the final pointer can be constified
that way.

Best regards,
Krzysztof
