[PATCH 16/25] media: i2c: ov2680: simplify getting state container
From: Krzysztof Kozlowski
Date: Mon Sep 21 2020 - 12:26:13 EST
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.
