[PATCH] fix compiler warning in sound/pci/cs46xx/cs46xx_lib.o

[Martin J. Bligh]

Fix the following compiler warning:
sound/pci/cs46xx/cs46xx_lib.c: In function `amp_voyetra':
sound/pci/cs46xx/cs46xx_lib.c:3384: warning: unused variable `old'
by wrapping the old variable in the same ifdef as its usage.
