Put the data availability checks behind a build option (new option CONFIG_DAI_VERBOSE_GLITCH_WARNINGS). In normal conditions, the DAI copy should never be called in a condition when there is no data to be copied. The audio interface is running and needs a constant stream of audio samples, so there is no remedy for not having data. In practise, most of the DAIs have a small buffer and can survive transient small gaps in data flow. The existing code has warning level logs for this condition. This is very useful for debug, as many common problems in firmware (and DSP topologies) show up as delays observed in the DAI copy logic. For product use, printing the warnings may make the situation worse by increasing the DSP load at a time when it has just missed a deadline. To allow for both debug and to avoid these checks in product builds, move the related checks behind a separate build option. Signed-off-by: Kai Vehmanen <kai.vehmanen@linux.intel.com>
