Subject: [PATCH v2 5/7] i2c: npcm: Modify the client address assignment
Date: Fri, 30 Aug 2024 11:46:38 +0800	[thread overview]
Message-ID: <20240830034640.7049-6-kfting@nuvoton.com> (raw)
In-Reply-To: <20240830034640.7049-1-kfting@nuvoton.com>

Store the client address earlier since it's used in the i2c_recover_bus
logic flow.

Fixes: 48acf8292280 ("i2c: Remove redundant comparison in npcm_i2c_reg_slave")
Signed-off-by: Tyrone Ting <kfting@nuvoton.com>
