4 Subject: [PATCH] media: i2c: ov9281: Fixup for recent kernel
5 releases, and remove custom code
6
7 The Rockchip driver was based on a 4.4 kernel, and had several custom
8 Rockchip parts.
9
10 Update to 5.4 kernel APIs, with the relevant controls required by
11 libcamera, and remove custom Rockchip parts.
