Hello Mengdong,

I know just as little as you do about Realtek ALC282. Chances are that 
Realtek haven't changed the codec much compared to ALC280, and then just 
another line next to the ALC280 would do just fine:

{ .id = 0x10ec0282, .name = "ALC282", .patch = patch_alc269 },

But I don't think Takashi would add such a line to the kernel without 
somebody testing that it actually works.
If you have the hardware available, you can try the above line, see if 
it works, and report back together with alsa-info for the affected system.
