isdn: whitespace coding style cleanup
isdn source code uses a not-current coding style.
Update the coding style used on a per-line basis
so that git diff -w shows only elided blank lines
at EOF.
Done with emacs and some scripts and some typing.
Built x86 allyesconfig.
No detected change in objdump -d or size.

isdn: fix possible circular locking dependency
There's a circular locking dependency:
---> isdn_net_get_locked_lp
--->lock &nd->queue_lock
--->lock &nd->queue->xmit_lock
.....................
---->unlock &nd->queue_lock
---> isdn_net_writebuf_skb (called with &nd->queue->xmit_lock locked)
---->isdn_net_inc_frame_cnt
---->isdn_net_device_busy
----> lock &nd->queue_lock
This will trigger lockdep warnings:
=======================================================
[ INFO: possible circular locking dependency detected ]
2.6.32-rc4-testing #7
-------------------------------------------------------
ipppd/28379 is trying to acquire lock:
(&netdev->queue_lock){......}, at: [<e62ad0fd>] isdn_net_device_busy+0x2c/0x74 [isdn]
but task is already holding lock:
(&netdev->local->xmit_lock){+.....}, at: [<e62aefc2>] isdn_net_write_super+0x3f/0x6e [isdn]
which lock already depends on the new lock.
.......
We don't need to lock nd->queue->xmit_lock to protect single
isdn_net_lp_busy(). This can fix above lockdep warnings.

isdn: Kill directly reference of netdev->priv
Simply use netdev_priv() to replace netdev->priv.

isdn: use %pI4, remove get_{u8/u16/u32} and put_{u8/u16/u32} inlines
They would have been better named as get_be16, put_be16, etc.
as they were hiding an endian shift inside.
They don't add much over explicitly coding the byteshifting
and gcc sometimes has a problem with builtin_constant_p inside
inline functions, so it may do a better job of byteswapping
at compile time rather than runtime.

__FUNCTION__ is gcc-specific, use __func__

Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
