[PATCH 02/12] ASoC: Intel: skl_hda_dsp_generic: Use devm_kasprintf for the components string

[Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>]

From: Peter Ujfalusi <peter.ujfalusi@xxxxxxxxxxxxxxx>

Instead of using a global char array, allocate the string with
devm_kasprintf if needed.
