regulators: helpers: Fix handling of bypass_val_on in get_bypass_regmap
The handling of bypass_val_on that was added in regulator_get_bypass_regmap is done unconditionally however several drivers don't define a value for bypass_val_on. This results in those drivers reporting bypass being enabled when it is not. In regulator_set_bypass_regmap we use bypass_mask if bypass_val_on is zero. This patch adds similar handling in regulator_get_bypass_regmap. Fixes: commit dd1a571daee7 ("regulator: helpers: Ensure bypass register field matches ON value") Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>
