[PATCH 3.16 093/136] ALSA: bebob: Fix prototype of helper function to return negative value

[Ben Hutchings]

3.16.80-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Sakamoto <o-takashi@xxxxxxxxxxxxx>

commit f2bbdbcb075f3977a53da3bdcb7cd460bc8ae5f2 upstream.

A helper function of ALSA bebob driver returns negative value in a
function which has a prototype to return unsigned value.

This commit fixes it by changing the prototype.
