Simple on/off conttrols should be _SINGLE controls with Switch at the end of their name. It's not super clear why this is in DAPM as a widget at all, the routing around it is:
+ {"BOOST Mux", "On", "Channel Mux"}, + {"CLASS H", NULL, "BOOST Mux"},
which is a bit perplexing. Possibly this should be handled in the event for the main amplifier?

These are just constants, why write out the operations?

This unconditionally reports that it handled the interrupt, even if it didn't. This will stop the interrupt core handling for faulty interrupt lines working and will disrupt any support that gets added for handling shared threaded interrupts.

Use { } on both sides of the if (see coding-style.rst)?

This doesn't handle -EPROBE_DEFER.
