Subject: [media] si2168: Fix i2c_add_mux_adapter return value
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4d6efc7a96c126f2b21ffd4edad9b11144a0336a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[media] si2168: Fix i2c_add_mux_adapter return value

In case of failure the return value was always 0. Return proper
error code (ENODEV) instead.
