Subject: [PATCH 4.14 64/95] ALSA: bebob: Fix prototype of helper function to return negative value
From: Takashi Sakamoto <o-takashi@...amocchi.jp>
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.
Fixes: eb7b3a056cd8 ("ALSA: bebob: Add commands and connections/streams management")
