Subject: ALSA: bebob: Use a signed return type for get_formation_index
From: Lucas Tanure <tanure@xxxxxxxxx>
commit 07905298e4d5777eb58516cdc242f7ac1ca387a2 upstream.
The return type "unsigned int" was used by the get_formation_index function
despite of the aspect that it will eventually return a negative error code.
So, change to signed int and get index by reference in the parameters.
Done with the help of Coccinelle.
[Fix the missing braces suggested by Julia Lawall -- tiwai]
