From 3a9dda79257589fe1ab10d0ce96b22e252354c6b Mon Sep 17 00:00:00 2001 From: Malcolm Priestley Date: Sun, 21 Dec 2014 12:56:35 +0000 Subject: [PATCH] staging: vt6655: Fix loss of distant/weak access points on channel change. If the asssocated access point is strong byBBVGACurrent will be adjusted accordingly. Users will nolonger see distant access points without taking down interface. When changing channel reset byBBVGACurrent back to pDevice->abyBBVGA[0] for max sensitivity.
