Subject: ACPI: sony-laptop.c: call acpi_get_object_info to get node info
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=30823736162ff91512965e3c730557e34fa71d6d;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

ACPI: sony-laptop.c: call acpi_get_object_info to get node info

Avoid using internal acpica structures acpi_namespace_node and acpi_operand_object
Call acpi_get_object_info to get node ascii name and method arg count
