Subject: [media] s5p-fimc: Fix bytesperline and plane payload setup
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=045030fa16648449b416d4fc8dcc54bfefd6f4aa;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[media] s5p-fimc: Fix bytesperline and plane payload setup

Make sure the sizeimage for 3-planar color formats is
width * height * 3/2 and the bytesperline is same for each
plane in case of a multi-planar format.
