From 4062b8ffec36df80d808d3bc3352e0f9c9abd3de Mon Sep 17 00:00:00 2001 From: Jes Sorensen Date: Thu, 14 Apr 2016 16:37:08 -0400 Subject: [PATCH] rtl8xxxu: Move PHY RF init into device specific functions Load the RF table in init_phy_rf(), which allows for applying device specific RF hacks in the same place. Getting rid of more ugly if () clutter.
