While looking for something else in the scan.c I noticed the room of improvement. Hence this series. Also bus.c patches, which some how were related to my research, but I think are independent from the scan.c improvements. Andy Shevchenko (7): ACPI: bus: Make container_of() no-op where it makes sense ACPI: bus: Don't use "proxy" headers ACPI: scan: Replace infinite for-loop with finite while-loop ACPI: scan: Use list_first_entry_or_null() in acpi_device_hid() ACPI: scan: Move misleading comment to acpi_dma_configure_id() ACPI: scan: Use standard error checking pattern ACPI: scan: Introduce typedef:s for struct acpi_hotplug_context members drivers/acpi/dock.c | 48 +++++++++++++++-------------------------- drivers/acpi/scan.c | 42 +++++++++++++++++------------------- include/acpi/acpi_bus.h | 28 +++++++++++++++--------- 3 files changed, 55 insertions(+), 63 deletions(-) -- 2.43.0.rc1.1.gbec44491f096
