In boards like adl_lt6911_hdmi_ssp/mtl_lt6911_hdmi_ssp/rpl_lt6911_hdmi_ssp, HDMI is supported both for playback via normal HDA display codec, as well as PCM capture from HDMI-In over I2S. The common board driver function hda_dsp_hdmi_pcm_handle() has an invalid assumption that "HDMI" is only used to identify playback HDMI PCMs on the card. This will result in failures if HDMI-In PCMs are defined in topology using the string "HDMI", and they are registered before the playback PCMs. Fix the issue by explicitly looking for FE playback PCMs. Signed-off-by: Kai Vehmanen <kai.vehmanen@linux.intel.com>
