[PATCH] sound/sound_core: Fix sparse warnings: returning void-valued expression and make 'soundcore_open' static

["Hannes Eder" <hannes@hanneseder.net>]

Fix the following sparse warnings:

sound/sound_core.c:460:2: warning: returning void-valued expression
sound/sound_core.c:477:2: warning: returning void-valued expression
sound/sound_core.c:510:5: warning: symbol 'soundcore_open' was not
declared. Should it be static?
