Why is this a module parameter - how would a user decide to set this? Is it something that someone might want to change at runtime?
While inserting this module we need to pass tdm_mode variable as 0 or 1 like below.
sudo insmod /lib/modules/$(uname -r)/kernel/sound/soc/amd/acp/snd-acp-mach.ko *tdm_mode=1*
Right, that's what the code does but why is this something that should be controlled in this fashion?
