From 56bde846304ea05d5f8c8de0e3a42627a7a92be6 Mon Sep 17 00:00:00 2001 From: Ping-Ke Shih Date: Thu, 17 Aug 2017 12:46:45 -0500 Subject: [PATCH] staging: r8822be: Add existing rtlwifi and rtl_pci parts for new driver The RTL8822BE, an 802.11ac wireless network card, is now appearing in new computers. Its driver is being placed in staging to reduce the time that users of this new card will have access to in-kernel drivers. This commit copies the code that currently constitutes the rtlwifi and rtl_pci mini drivers. This material is copied into staging to prevent any undo interaction between the existing drivers and this new one. The only changes in this code are the removal of all export statements, and the fixing of some checkpatch messages. The latter will be backported into the wireless tree.
