From 4f4826da8cae59c167fc730b5db6f0659c2d37ce Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Thu, 26 Sep 2013 13:25:27 -0500 Subject: [PATCH] rtlwifi: Implement a common rtl_phy_scan_operation_backup() routine Several of the drivers supported by rtlwifi individually implement the same routine that supports scans. As a first step, create this routine in driver rtlwifi. Signed-off-by: Larry Finger Signed-off-by: John W.
