Revision eb72d5207008db54c659fd34f341672decc306ae authored by Charles Keepax on 19 September 2023, 11:03:20 UTC, committed by Linus Torvalds on 23 September 2023, 18:10:23 UTC 
mfd: cs42l43: Use correct macro for new-style PM runtime ops
 
The code was accidentally mixing new and old style macros, update the
macros used to remove an unused function warning whilst building with
no PM enabled in the config.
