Subject: [PATCH] sound: fix kernel-doc build warning

From: Randy Dunlap <rdunlap@...radead.org>

Fix kernel-doc build error. A symbol that ends with an underscore
character ('_') has special meaning in reST (reStructuredText), so add
a '*' to prevent this error and to indicate that there are several of
these values to choose from.

../sound/core/jack.c:312: ERROR: Unknown target name: "snd_jack_btn".
