ALSA: bebob: Use a signed return type for get_formation_index
[ Upstream commit 07905298e4
]
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]
