Subject: [PATCH] hwmon: (pmbus/mp9941) Add missing bitfield header

The recently added driver for the MP99441 is missing the bitfield
header. Without it, gcc fails to find FIELD_PREP and FIELD_GET.

Add the missing <linux/bitfield.h>

Reported-by: kernel test robot <lkp@...el.com>
Fixes: c16fa6967781 ("hwmon: add MP9941 driver")
Signed-off-by: Javier Carrasco <javier.carrasco.cruz@...il.com>

This patch fixes the errors reported by the kernel test robot about
the MP9941 in the hwmon subsystem. It does not close the error report
from the BUILD REGRESSION 6906a84c482f098d31486df8dc98cead21cce2d0,
that includes, among others, this issue. The report attached to the
mentioned build regression actually covers a different bug.
Hence why no Closes: tag was added.
