[PATCH AUTOSEL 5.12 16/33] regulator: hi6421v600: Fix .vsel_mask setting

[PATCH AUTOSEL 5.12 16/33] regulator: hi6421v600: Fix .vsel_mask setting

[Sasha Levin]

From: Axel Lin <axel.lin@ingics.com>

[ Upstream commit 50bec7fb4cb1bcf9d387046b6dec7186590791ec ]

Take ldo3_voltages as example, the ARRAY_SIZE(ldo3_voltages) is 16.
i.e. the valid selector is 0 ~ 0xF.
But in current code the vsel_mask is "(1 << 15) - 1", i.e. 0x7FFF. Fix it.
