bus: qcom: Put child node before return
[ Upstream commit ac6ad7c2a862d682bb584a4bc904d89fa7721af8 ]
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.
