Re: Kernel 5.2.8 - au0828 - Tuner Is Busy

[Nathan Royce <nroycea+kernel@gmail.com>]

While your mention of quirks-table.h certainly had possibilities, I'm
afraid adding the "AU0828_DEVICE(0x05e1, 0x0400, "Hauppauge",
"Woodbury")," entry for my tuner did not make any difference regarding
the "Tuner is busy. Error -19" message.

I don't know if this means anything, but I see
https://patchwork.kernel.org/patch/97726/ from 2010 which contains
changes for the 0x0400 model. I guess it never got pulled in.

Really, it's fine for me just to hang back at v5.1 for a year or two
until ATSC 3.0 USB tuners come out at a reasonable price.
