Subject: [PATCH v6 3/4] media: i2c: imx258: simplify getting state container
Date: Wed, 18 Nov 2020 21:27:14 +0100 [thread overview]
Message-ID: <20201118202715.6692-3-krzk@kernel.org> (raw)
In-Reply-To: <20201118202715.6692-1-krzk@kernel.org>
The pointer to 'struct v4l2_subdev' is stored in drvdata via
v4l2_i2c_subdev_init() so there is no point of a dance like:
struct i2c_client *client = to_i2c_client(struct device *dev)
struct v4l2_subdev *sd = i2c_get_clientdata(client);
This allows to remove local variable 'client' and few pointer
dereferences.
