Subject: ACPI: PM: Unify debug messages in acpi_device_set_power()
X-Git-Tag: v5.19-rc1~183^2~1^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f4f3548dc8d53d683770b058fdafa01fd7c07669;p=thirdparty%2Fkernel%2Flinux.git

ACPI: PM: Unify debug messages in acpi_device_set_power()

Convert all of the debug messages printed by acpi_device_set_power()
to acpi_handle_debug() and adjust them slightly for consistency with
acpi_device_get_power() and other acpi_device_set_power() debug
messages.
