Subject: media: i2c: ov4689: Remove i2c_client from ov4689 struct
Author: Mikhail Rudenko <mike.rude...@gmail.com>
Date: Tue Apr 16 23:45:13 2024 +0100
The 'client' field within the 'ov4689' structure is solely used to
access its 'dev' member. This commit removes the 'client' field and
directly stores a pointer to the 'struct device'.
