I'd like to move this into sound/core. Also, the kconfig name appears a bit too lengthy to me.

This should be bool "Sound Proc FS Support" if !SND_REDUCED_MEMORY_FOOTPRINT depends on PROC_FS
In this way, this prompt would appear only when SND_REDUCED_MEMORY_FOOTPRINT is set, i.e. only for experts.
