From 570d785ba46b947e0ded0c38955c43d1d7867c12 Mon Sep 17 00:00:00 2001 From: Kelsey Skunberg Date: Wed, 24 Jul 2019 00:06:59 -0600 Subject: [PATCH] drivers: net: xgene: Remove acpi_has_method() calls acpi_evaluate_object will already return an error if the needed method does not exist. Remove unnecessary acpi_has_method() calls and check the returned acpi_status for failure instead. Signed-off-by: Kelsey Skunberg Signed-off-by: David S.
