Rafael as ACPI maintainer thinks the helper makes sense and therefore acked it. Andi shares this opinion, and others like Jean have doubts. For sure I won't receive a Turing award for this helper, but it's IMO better than the cascaded macros.

In several drivers devices use the ACPI companion of the parent. Add a helper for this use case to avoid code duplication. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> --- include/linux/acpi.h | 5 +++++ 1 file changed, 5 insertions(+)
