Subject: [PATCH] ASoC: da7218: fix fix child-node lookup
Git-commit: bc6476d6c1edcb9b97621b5131bd169aa81f27db
Patch-mainline: v4.15-rc6
References: bsc#1051510
Fix child-node lookup during probe, which ended up searching the whole
device tree depth-first starting at the parent rather than just matching
on its children.
To make things worse, the parent codec node was also prematurely freed.
Fixes: 4d50934abd22 ("ASoC: da7218: Add da7218 codec driver")
