Comment 13 for bug 1749961

Hello,

I am unable to test with the kernel you provided, because my tuner card doesn't have driver in mainline kernel tree. So I have to compile it myself and I need kernel headers for this.

So I compiled kernel 4.16 from debian linux-source-4.16 package and applied the patch you provided:

Compiled my tuner card driver now and I am testing.
