Date: Wed, 13 Sep 2006 13:50:12 -0500 From: Corey Minyard <minyard@....org> To: Andrew Morton <akpm@...l.org>, Linux Kernel <linux-kernel@...r.kernel.org> Cc: Matt Domsch <Matt_Domsch@...l.com> Subject: [PATCH] IPMI: fix handling of OEM flags If one of the OEM flags becomes set in the flags from the hardware, the driver could hang if no OEM handler was set. Fix the code to handle this. This was tested by setting the flags by hand after they were fetched.
