ASoC: soc-core.c: Skip dummy codec when adding platforms
[ Upstream commit 23fb6bc2696119391ec3a92ccaffe50e567c515e ]
When pcm_runtime is adding platform components it will scan all
registered components. In case of DPCM FE/BE some DAI links will
configure dummy platform. However both dummy codec and dummy platform
are using "snd-soc-dummy" as component->name. Dummy codec should be
skipped when adding platforms otherwise there'll be overflow and UBSAN
complains.
