[PATCH v4 0/4] Use helper function for_each_child_of_node_scoped()

[Ai Chao]

This patch series introduces wrapper functions for_each_child_of_node_scoped().

The for_each_child_of_node_scoped() helper provides a scope-based clean-up
functionality to put the device_node automatically, and as such, there is
no need to call of_node_put() directly.

 - Patch 1 ALSA: ppc: Use helper function for_each_child_of_node_scoped()

 - Patch 2 ASoC: renesas: Use helper function for_each_child_of_node_scoped()
