X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=61b0088b6a5b98608ce00c18a057b1f5bcb5f8b3;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ASoC: Bind new DAI links after probing components

Probing components can bring new DAI or DAI links based on the topology
info. This patch finds the unbound DAI links and bind them.
