Subject: [PATCH] mfd:i2c: remove redundant dev_set_drvdata() function
Date:   Wed, 29 Mar 2023 13:57:24 +0800
Message-Id: <20230329055724.43998-1-aarongt.shen@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

the i2c_set_clientdata() is the inline function which is
complemented by the dev_set_drvdata() internally. Do not
need to use the i2c_set_clientdata() and dev_set_drvdata()
at the same time.
