From: Johannes Berg Date: Thu, 1 Jun 2017 09:37:25 +0000 (+0200) Subject: iwlwifi: mvm: remove version 2 of paging command X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4f2210ee8498faa3499a927f0a40027ff972ec3a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git 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.
