Subject: [PATCH 3/4] wl12xx: add module_param to trigger BUG() on recovery
Date: Thu, 25 Aug 2011 18:10:59 +0300	[thread overview]
Message-ID: <1314285060-5088-3-git-send-email-eliad@wizery.com> (raw)
In-Reply-To: <1314285060-5088-1-git-send-email-eliad@wizery.com>

Crashing on recovery is useful for debugging, as a JTAG
can be connected in order to investigate the current fw state.
(otherwise, a reconfiguration will occur)
