From 1568426c491ad7e17a8d9e0e4d3397ee107af899 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 1 Feb 2019 10:58:20 +0100 Subject: [PATCH] ACPI: EC: Make acpi_ec_ecdt_probe() more straightforward Since acpi_ec_ecdt_probe() is called when boot_ec is not set, it doesn't neeed to take the other possibility into account. Accordingly, it only needs to set the handle field in the ec object to ACPI_ROOT_OBJECT, call acpi_ec_setup() and (if that is successful) set boot_ec to ec and boot_ec_is_ecdt to 'true'. Make it do so directly, without calling acpi_config_boot_ec(), and avoid some pointless checks in the latter. No intentional functional impact except for a changed message. Signed-off-by: Rafael J.
