However, not initializing all members may cause subtle issues, which are only exposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is enabled. Hence this series aims to make sure all members are fully initialized, to avoid such bugs, and to prevent future breakage when converting drivers to a different method for specifying the parents. Part One[1] fixed all cases that I identified to be real bugs, in response to a crash I saw on BeagleBone Black. This series is the PHY subpart of Part Two, which fixes remaining cases that are currently harmless. These are still fragile, and may cause future breakage when converting drivers to a different method for specifying the parents. Thanks for your comments!
