Subject: [PATCH] iwlwifi: mvm: fix interface bringup on non-ACPI configs
Date:   Thu, 21 Nov 2019 15:48:32 +0800
Message-Id: <20191121074832.6978-1-git@xen0n.name>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-wireless-owner@vger.kernel.org
Precedence: bulk

Previously the non-ACPI stub of iwl_mvm_ppag_init unconditionally
returned -ENOENT, that in turn blocked flow of iwl_mvm_up.

Take the precedent of iwl_mvm_sar_geo_init, make iwl_mvm_ppag_init no-op
on non-ACPI configs.
