However, the hardware also accepts sizes divisible by 4 bytes, which are needed to fully utilize the S5K3L6XX sensors. This patch accepts line sizes divisible by 4 bytes. Signed-off-by: Dorota Czaplejewicz --- Hello, the Librem 5 is using an out-of-tree driver for s5k3l6xx, and rounding to 4 is optimal to operate it. This revision improves the commit message.
