The removed dai_link->platform component cause a fail which is exposed at runtime. (ex: when a sound tool is used) This patch re-adds the dai_link->platform component to have a full card registered. Before this patch: $ aplay -l **** List of PLAYBACK Hardware Devices **** card 1: HDMI [HDMI], device 0: HDMI snd-soc-dummy-dai-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 $ speaker-test -D plughw:1,0 -t sine speaker-test 1.2.8 Playback device is plughw:1,0 Stream parameters are 48000Hz, S16_LE, 1 channels Sine wave rate is 440.0000Hz Playback open error: -22,Invalid argument After this patch which restores the platform component: $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: HDMI [HDMI], device 0: HDMI snd-soc-dummy-dai-0 [HDMI snd-soc-dummy-dai-0] Subdevices: 0/1 Subdevice #0: subdevice #0 -> Resolve the playback error.
