Comment 24 for bug 871808

I used [url=http://www.question-defense.com/2010/09/26/how-to-recompile-your-ubuntu-10-10-kernel-for-patching-or-to-add-support-for-a-specific-device]this[/url] manual to download and prepare the kernel, then tried to apply the patch at step 5 with the command you issued using the nx5.patch from the 2012-01-05 post.
It then comes up with the following error:

~/source/linux-3.0.0# patch -p1 < nx5.patch
The next patch would create the file sound/pci/hda/alc662_asus_nx5_quirks.c,
which already exists! Assume -R? [n] n
Apply anyway? [n] n
Skipping patch.
1 out of 1 hunk ignored
can't find file to patch at input line 117
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:

|diff --git a/sound/pci/hda/alc662_quirks.c b/sound/pci/hda/alc662_quirks.c

I think I'm close, but don't know how to fix it.
