[alsa-devel] [PATCH 4/6] ALSA: dice: simplify symbol space for local linkage

[Takashi Sakamoto]

This module has some implementations for operation structures which sound
subsystem defines. All of them are referred just by each local function to
register corresponding operations. In this case, it's better to put them
into the function local so that symbol space in local linkage of
translation unit is kept to be simple.

This commit moves such symbols to function local.
