I will replace with dev_err(). I need to check if HDMI display is active
because the HDMI DSS driver is in charge of powering on/off the HDMI IP.
Audio can play only if the HDMI IP is on. I don't have a .trigger
function in my DAI so I thought it was OK to perform the check
at .startup. Do you think I should create a .trigger function and
perform the check from there?

I will add.
