Subject: [PATCH linux-next] snd-hda: fix build errors

From: Randy Dunlap <randy.dunlap@...cle.com>

First error comes from snd_hda_eld_proc_new() not being static
when CONFIG_PROC_FS=n.  After that is fixed, the next problem is:
ERROR: "snd_print_pcm_rates" [sound/pci/hda/snd-hda-intel.ko] undefined!

so I made a static inline version of that one too, for CONFIG_PROC_FS=n.
Please build/test more config variations.
