UCM2 Conditional cset in BootSequence

Hello,

I'm writing a UCM2 .conf file, depending on Device Tree options, some kcontrols may or may not exist - how do I handle this in the BootSequence, so alsactl does not error out if some controls don't exist?

I know there's a possible If condition to check if a control exists, but how do I use that to conditionally append to the BootSequence?

Thank you! Giedrius.
