Subject: [PATCH AUTOSEL 5.12 16/33] regulator: hi6421v600: Fix .vsel_mask setting
Date: Tue, 15 Jun 2021 11:48:07 -0400 [thread overview]
Message-ID: <20210615154824.62044-16-sashal@kernel.org> (raw)
In-Reply-To: <20210615154824.62044-1-sashal@kernel.org>
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.
