- After we unregister a kobject, wait for our kobject release method
  to call complete().  This causes us to wait until the kobject
  reference count reaches 0.  Otherwise, a task accessing the EDAC
  sysfs interface can hold the reference count above 0 until after the
  EDAC module has been unloaded.  When the reference count finally
  drops to 0, this will result in an attempt to call our release
  method inside the EDAC module after the module has already been
  unloaded.

  This isn't the best fix, since a process can get stuck sleeping forever
  uninterruptibly if the user does the following:

      rmmod my_module < /sys/my_sysfs/file

  I'll go back and implement a better fix later.  However this should
  be ok for now.

- Call edac_remove_sysfs_mci_device() from edac_mc_del_mc() rather
  than from edac_mc_free().  Since edac_mc_add_mc() calls

  edac_remove_sysfs_mci_device().

The following patches add drivers for the Siemens Gigaset 3070 family of ISDN
DECT PABXes connected via USB, either directly or over a DECT link using a
Gigaset M105 or compatible DECT data adapter.  The devices are integrated as
ISDN adapters within the isdn4linux framework, supporting incoming and
outgoing voice and data connections, and also as tty devices providing access
to device specific AT commands.

Supported devices include models 3070, 3075, 4170, 4175, SX205, SX255, and
SX353 from the Siemens Gigaset product family, as well as the technically
identical models 45isdn and 721X from the Deutsche Telekom Sinus series.
Supported DECT adapters are the Gigaset M105 data and the technically
identical Gigaset USB Adapter DECT, Sinus 45 data 2, and Sinus 721 data (but
not the Gigaset M34 and Sinus 702 data which advertise themselves as CDC-ACM
devices).

These drivers have been developed over the last four years within the
SourceForge project http://sourceforge.net/projects/gigaset307x/.  They are
being used successfully in several installations for dial-in Internet access
and for voice call switching with Asterisk.

This is our second attempt at submitting these drivers, taking into account
the comments we received to our first submission on 2005-12-11.

The patch set adds three kernel modules:

- a common module "gigaset" encapsulating the common logic for
  controlling the PABX and the interfaces to userspace and the
  isdn4linux subsystem.

- a connection-specific module "bas_gigaset" which handles
  communication with the PABX over a direct USB connection.

- a connection-specific module "usb_gigaset" which does the same
  for a DECT connection using the Gigaset M105 USB DECT adapter.

We also have a module "ser_gigaset" which supports the Gigaset M101 RS232 DECT
adapter, but we didn't judge it fit for inclusion in the kernel, as it does
direct programming of a i8250 serial port.  It should probably be rewritten as
a serial line discipline but so far we lack the neccessary knowledge about
writing a line discipline for that.

The drivers have been working with kernel releases 2.2 and 2.4 as well as 2.6,
and although we took efforts to remove the compatibility code for this
submission, it probably still shows in places.  Please make allowances.

This patch:

Prepare the kernel build infrastructure for addition of the Gigaset ISDN
drivers.  It creates a Makefile and Kconfig file for the Gigaset driver and
hooks them into those of the isdn4linux subsystem.  It also adds a MAINTAINERS
entry for the driver.

This patch depends on patches 2 to 9 of the present set, as without the actual
source files, activating the options added here will cause the kernel build to
fail.
