It would be nice to have KUnit coverage for the new function too.

  regmap: Implement regmap_multi_reg_read() (2024-07-10 18:45:34 +0100)

----------------------------------------------------------------
regmap: Implement regmap_multi_reg_read()

A new API function from Guenter Roeck:

regmap_multi_reg_read() is similar to regmap_bulk_read() but reads from
an array of non-sequential registers. It is helpful if multiple non-
sequential registers need to be read in a single operation which would
otherwise have to be mutex protected.

The name of the new function was chosen to match the existing function
regmap_multi_reg_write().
