Subject: linux-next: build warning after merge of the regulator tree

Hi all,

After merging the regulator tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

In file included from drivers/regulator/mpq7920.c:19:
drivers/regulator/mpq7920.c: In function 'mpq7920_parse_cb':
drivers/regulator/mpq7920.c:224:13: warning: conversion from 'long unsigned int' to 'unsigned int' changes value from '18446744073709551551' to '4294967231' [-Woverflow]
  224 |     BIT(6), ~BIT(6));
include/linux/regmap.h:75:42: note: in definition of macro 'regmap_update_bits'
   75 |  regmap_update_bits_base(map, reg, mask, val, NULL, false, false)
      |                                          ^~~

Introduced by commit
