Subject: V4L/DVB (11911): cx231xx: Use v4l bounding/alignment function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9bd0e8d7d1bf0dc586bad905c7878b611da3acdc;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

V4L/DVB (11911): cx231xx: Use v4l bounding/alignment function

The v4l function has a better algorithm for aligning image size.
