From 4f2210ee8498faa3499a927f0a40027ff972ec3a Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 1 Jun 2017 11:37:25 +0200 Subject: [PATCH] iwlwifi: mvm: remove version 2 of paging command Only a000-series devices were going to use this, but actually initialize using the context info, which includes paging, so this code is never invoked; remove it.
