[ Upstream commit ff04437f6dcd138b50483afc7b313f016020ce8f ]
When changing value of kcontrol, FW module to which data should be send needs to be found. Currently it is done in improper way, fix it. Change function name to indicate that it looks only for volume module.
This allows to change volume during runtime, instead of only changing init value.
