Subject: [media] tuner-core: Remove V4L1/V4L2 API switch
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5620094a2eaa6527d7f038ad3d65ce6a76c8272a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[media] tuner-core: Remove V4L1/V4L2 API switch

V4L1 was removed. So, the code there is just dead code.
