After the last "package" of firmware data is sent to the device, we dereference
NULL pointer (on access to rec->addr). Fix it.

usb: auerswald: remove driver (obsolete)

2008-08-14T00:32:47+00:00

This patch removes the auerswald USB driver from the linux kernel
2.6.26.

This driver was included into the kernel mainly to connect to the ISDN
framework. This was done in linux 2.4.x. For 2.6.x, due to the fragile
and moving ISDN support, this connection was never realized, and the
only use of this driver was for device configuration. In the age of DSL,
the demand of ISDN support is getting very low.

Meanwhile, with the advent of libusb, an userspace driver was done for
the device configuration which works fine for linux and mac. (Thanks to
the libusb developers!). The userspace driver is downloadable from the
auerswald web site.

So this driver is obsolete now and has to be removed. Many thanks to all
developers which helped me to bring this driver up and working.

Rename WARN() to WARNING() to clear the namespace

2008-07-25T17:53:29+00:00

We want to use WARN() as a variant of WARN_ON(), however a few drivers are
using WARN() internally.  This patch renames these to WARNING() to avoid the
namespace clash.  A few cases were defining but not using the thing, for those
cases I just deleted the definition.

This is another case where the lock_kernel appears to be unneccessary and

The BKL is actually probably not needed as the mutex seems sufficient. If
so then a further patch to drop it would be a good followup.

I'm pretty sure the mutex is sufficient for all locking but will come
back to that later if the USB folks don't beat me to it. For now get rid
of the old BKL ioctl method and wrap the ioctl handler
