From c746b6b67e168f27b04563b0b429aa3e8be27011 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 1 Feb 2019 10:59:42 +0100 Subject: [PATCH] ACPI: EC: Make acpi_ec_dsdt_probe() more straightforward Since acpi_ec_dsdt_probe() returns early if boot_ec is set, it is always unset when that function calls acpi_config_boot_ec() (passing ec->handle as the handle argument to it). Thus it is not really useful to call acpi_config_boot_ec() at that point. It is sufficient to call acpi_ec_setup() directly and (if that is successful) set boot_ec, so make acpi_ec_dsdt_probe() do that and avoid some pointless checks in acpi_config_boot_ec(). No intentional functional impact except for a changed message. Signed-off-by: Rafael J.
