5eecd8ea7d svolume: tweak constraints for 32 bits 
Tweak the constraints a little so that register starved 32bit systems
can select a stack variable for the channel paramter instead of reusing one of
the registers we're using in the code.

a98fa950d2 svolume: remove unneeded compare 
We don't need the compare because the sub operation already set the right flags
for us.
