ENGR00255482 ASoC: HDMI-audio: Add error message for HDMI-video detect failure HDMI-audio depends on HDMI-video. If users want to use HDMI-audio function, they need to load HDMI-video first. Sometime users would forget to put video info into U-boot cmdline, "video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24" for example. That might cause HDMI-auido driver fail to detect HDMI-video. Previously, if this happened to system, driver only returned with "ENOMEM" and system would print "Can't allocate memory". This might confuse users due to the vague infomation. Users would be hard to figure out the root cause. So this patch just add some error message to give users a clear indication, and changed the "ENOMEM" error number to the more precise "ENODEV".
