Hmm. Decided to test it. It warns for every case: a bit excessive,
perhaps, but I guess it won't hurt.

So Shuah's thing results in

[    9.791367] Call Trace:
WARNING! Modules path isn't set, but is needed to parse this symbol
[    9.791377] ? snd_pcm_hw_params+0x3ca/0x440 snd_pcm
WARNING! Modules path isn't set, but is needed to parse this symbol

WARNING! Modules path isn't set, but is needed to parse this symbol

WARNING! Modules path isn't set, but is needed to parse this symbol
[    9.791394] snd_pcm_ioctl+0x27/0x40 snd_pcm

which looks a bit redundant, but maybe that just means people _really_ notice.

So the patch stays.
