Subject: [PATCH] bus: qcom: Put child node before return
Git-commit: ac6ad7c2a862d682bb584a4bc904d89fa7721af8
Patch-mainline: v5.13-rc1
References: git-fixes
Put child node before return to fix potential reference count leak.
Generally, the reference count of child is incremented and decremented
automatically in the macro for_each_available_child_of_node() and should
be decremented manually if the loop is broken in loop body.
