Use the normal kernel debugging mechanism which also
enables dynamic_debug at the same time.
Other miscellanea:
o Remove sysctl for irda_debug
o Remove function tracing like uses (use ftrace instead)
o Coalesce formats
o Realign arguments
o Remove unnecessary OOM messages

And use the more common mechanisms directly.
Other miscellanea:
o Coalesce formats
o Add missing newlines
o Realign arguments
o Remove unnecessary OOM message logging as
there's a generic stack dump already on OOM.

Several files refer to an old address for the Free Software Foundation
in the file header comment. Resolve by replacing the address with
the URL <http://www.gnu.org/licenses/> so that we do not have to keep
updating the header comments anytime the address changes.

There are a mix of function prototypes with and without extern
in the kernel sources. Standardize on not using extern for
function prototypes.
Function prototypes don't need to be written with extern.
extern is assumed by the compiler. Its use is as unnecessary as
using auto to declare automatic/local variables in a block.

It's convenient to have ethernet mac addresses use
ETH_ALEN to be able to grep for them a bit easier and
also to ensure that the addresses are __aligned(2).
Add #include <linux/if_ether.h> as necessary.

The "reason" can come from skb->data[] and it hasn't been capped so it
can be from 0-255 instead of just 0-6. For example in irlmp_state_dtr()
the code does:
reason = skb->data[3];
...
irlmp_disconnect_indication(self, reason, skb);
Also LMREASON has a couple other values which don't have entries in the
irlmp_reasons[] array. And 0xff is a valid reason as well which means
"unknown".
So far as I can see we don't actually care about "reason" except for in
the debug code.

This also includes a switch to tty refcounting. It makes sure, the
code no longer can access a freed TTY struct.
Sometimes the only thing needed is to pass tty down to the callies.

Use self->spinlock only for ctrl_skb and tx_skb. TTY stuff is now
protected by tty_port->lock. This is needed for further cleanup (and
conversion to tty_port helpers).
This also closes the race in the end of close.

We don't actually need this and it causes problems for internal use of
this functionality. Currently there is a single use of the FILE * pointer.
That is the serial core which uses it to check tty_hung_up_p. However if
that is true then IO_ERROR is also already set so the check may be removed.
