From 78de2c063710988b5bf0883c186c366e997c3193 Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Wed, 21 May 2014 16:25:33 -0500 Subject: [PATCH] staging: r8192ee: Add source files for core driver This part is the equivalent of rtlwifi in the wireless tree. As the changes needed for the RTL8192EE have not yet been merged, a separate version is still needed.
