Subject: V4L/DVB (8682): V4L: fix return value of register video func
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=46f2c21cfdb1a829a9a23e23562ffa66b007dc48;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

V4L/DVB (8682): V4L: fix return value of register video func

If a wrong device type is used with video_register_device_index() it should
better return an error number, instead of a constant.
