[alsa-devel] [PATCH] ASoC: dapm: Remove snd_soc_of_parse_audio_routing() due to deferred probe
This reverts commit f8781db8aeb18d (ASoC: dapm: Augment existing card DAPM routes in snd_soc_of_parse_audio_routing) since it is broken for deferred probing as it ends up storing data allocated with devm_ over multiple instantiations of the device.

Great news, the SDP4430 now boots again. Thanks for the fix, and Merry Christmas.
