Message-ID: <538C953B.9020304@mutualink.net> Date: Mon, 02 Jun 2014 11:16:11 -0400 From: Mike Remski <mremski@...ualink.net> To: Johan Hovold <jhovold@...il.com> CC: linux-kernel@...r.kernel.org, linux-usb@...r.kernel.org Subject: Re: ftdi_sio BUG: NULL pointer dereference Thanks Johan, that's why I looked at the cross references for ftdi_sio.c over on http://lxr.free-electrons.com/source/drivers/usb/serial/ftdi_sio.c, latest version it's showing is 3.14. It appears that the ftdi_sio code is largely the same as in 2.6.32, particularly in the ftdi_set_max_packet_size() function. I'm trying to verify if the "number of endpoints is 0" is a valid situation. Just a typical day of "fun with kernels and devices".
