locking init cleanups:
- convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK()
- convert rwlocks in a similar manner
this patch was generated automatically.
Motivation:
- cleanliness
- lockdep needs control of lock initialization, which the open-coded
variants do not give
- it's also useful for -rt and for lock debugging in general

Using the class device pointer returned by tty_register_device() with
part 1 of the patch, attach the Gigaset drivers' "cidmode" sysfs entry
to its tty class device, where it can be found more easily by users
who do not know nor care which USB port the device is attached to.

Fix a possible Oops in the Siemens Gigaset base driver when the device is
unplugged while an ISDN connection is still active, and makes sure that the
isdn4linux link level (LL) is properly informed if a connection is broken
by the USB cable being unplugged.
- Avoid unsafe checks of URB status fields outside the URB completion
handlers, keep track of in-use URBs myself instead.
- If an isochronous transfer URB completes with status==0, also check the
status of the frame descriptors.
- Verify length of interrupt messages received from the device.
- Align the length limit on transmitted AT commands with the device
documentation.
- In case of AT response receive overrun, keep newly arrived instead of old
unread data.
- Remove redundant check of device ID in the USB probe function.
- Correct and improve some comments and formatting.

Improve error reporting of the Gigaset drivers, by using the
dev_err/dev_warn/dev_info macros from device.h instead of err/warn/info from
usb.h whereever possible.
Also rename the private dbg macro to gig_dbg in order to avoid confusion with
the macro of the same name in usb.h.

This patch adds the common include file for the Siemens Gigaset drivers,
providing definitions used by all of the Gigaset ISDN driver source files. It
also adds the main source file of the gigaset module which manages common
functions not specific to the type of connection to the device.
