Subject: [PATCH] regulator: fan53880: Fix vsel_mask setting for FAN53880_BUCK
Date: Mon,  7 Jun 2021 22:29:07 +0800	[thread overview]
Message-ID: <20210607142907.1599905-1-axel.lin@ingics.com> (raw)

According to the datasheet:
REGISTER DETAILS − 0x02 BUCK, BUCK_OUT is BIT0 ~ BIT7.

So vsel_mask for FAN53880_BUCK should be 0xFF.

Fixes: e6dea51e2d41 ("regulator: fan53880: Add initial support")
