From a3ad38e87eead6ce748c6e4eec0571ce53b5a0c2 Mon Sep 17 00:00:00 2001 From: "armadefuego@gmail.com" Date: Tue, 22 Mar 2011 09:49:15 -0700 Subject: [PATCH] orinoco: Clear dangling pointer on hardware busy On hardware busy the scan request pointer should be cleared, as higher levels will release. This avoids a crash when that pointer is erroneously used later. Signed-off-by: Joseph J. Gunn Signed-off-by: John W.
