From 3d5201233ad593edc92e6fb6eb3838e0158df988 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Mon, 21 Sep 2020 18:23:25 +0200 Subject: [PATCH] media: i2c: ad5820: simplify getting state container 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.
