[PATCH v10 05/11] regulator: move rdev_print helpers to internal.h

[Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>]

[-- Attachment #1: Type: text/plain, Size: 4572 bytes --]

The rdev print helpers are a nice way to print messages related to a
specific regulator device. Move them from core.c to internal.h

As the rdev print helpers use rdev_get_name() export it from core.c. Also
move the declaration from coupler.h to driver.h because the rdev name is
not just a coupled regulator property. I guess the main audience for
rdev_get_name() will be the regulator core and drivers.
