Comment(by amistry at uwaterloo.ca):

 Stuart:  You're right, it is broken, but only with respect to logging
 info.  The point of the repeated checking is to give the function a single
 return point at the end of the function.  This way, I only have to do any
 potential cleanup at one point, at the end.  All the 'if (0 <= retval)' is
 there to make sure further code only executes if everything up until that
 point is OK.  If it's not, it'll be skipped and a return code of < 0
 (usually -1) will signify an error.  You'll notice all the functions I've
 wrote are like that inclusing the alsa input.  If for some reason this is
 unacceptable, I can rework the patch to put returns after each error
 instead of just at the end.
