Hello. I tested the code that "#define XXXX_DEBUG 0" on our company EVB with WM8960. I defined "#define XXXX_DEBUG 0" and dbg() put into mute function(wm8960_digital_mute()). After linux boot, played audio file. My test dbg() message was not print terminal, but I find dbg() code was working exactly. Excuted dmesg command, then it was print that logged dbg() messages. I think, it maybe potential that reduce performance before one knows. Thanks.
