Subject: [PATCH v2 08/11] i2c: npcm: Correct register access width
Date:   Sun, 20 Feb 2022 11:53:18 +0800
Message-Id: <20220220035321.3870-9-warp5tw@gmail.com>
In-Reply-To: <20220220035321.3870-1-warp5tw@gmail.com>
References: <20220220035321.3870-1-warp5tw@gmail.com>
Precedence: bulk

From: Tyrone Ting <kfting@nuvoton.com>

Use ioread8 instead of ioread32 to access the SMBnCTL3 register since
the register is only 8-bit wide.
