From 2a5bff091f4c32d07f007d6491453b67b497a3a4 Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Thu, 25 Aug 2011 18:10:59 +0300 Subject: [PATCH] wl12xx: add module_param to trigger BUG() on recovery Crashing on recovery is useful for debugging, as a JTAG can be connected in order to investigate the current fw state.
