From c2ac90b9b4c178936396deb67451e3850c0e5204 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 6 Jun 2013 10:30:49 +0300 Subject: [PATCH] Staging: rtl8192u: fix a reversed test Sean MacLennan fixed this in the rtl8192e driver and we should fix it here as well. It's pretty harmless. This information comes from the firmware, if we were to hit this bug we would read beyond the end of the array once or twice before returning and update our statistics with bogus data.
