From f7e6469fc90aa388ac5047e1ba914b31af9240ae Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 23 Jun 2015 21:58:17 +0200 Subject: [PATCH] iwlwifi: remove command and return value from opmode RX With the previous patch series, no opmode continues using the command or handler_status (i.e. the return value from the RX) so it can be removed now.
