staging: regulator: hi6421v600-regulator: cleanup debug messages
- use dev_foo() instead of pr_foo(); - cleanup the messages, making them more standard and easier to understand. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Link: https://lore.kernel.org/r/2d17e168031340da73e1bd1c826289ceba2dbe8f.1597647359.git.mchehab+huawei@kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
