[PATCH 3/4] ALSA: riptide: Reduce the scope for two variables in snd_riptide_proc_read()

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 17 Nov 2017 09:55:27 +0100

Move the definitions for the local variables "lval" and "rval" into
an if branch so that the corresponding setting will only be performed
on concrete demand in this function.
