serial_8250: pci_enable_device fail is not fully handled
<rmk> talking about leaks - I noticed that the 'check return of
pci_enable_dev()' in the 8250 pci resume function finally made it in
despite my objections against it (causing stuff in higher levels to
leak).

usb: fix pl2303 initialization
This patch removes the private check for the termios_initialized for
the pl2303 usb driver. It forced the baud to 9600 on the first call
to pl2303_set_termios()
Based on the tty changes in the 2.6.27 kernel, the termios passed to
the *_set_termios functions is always populated the first time.
This means there is no need to privately initialize the settings the
first time, and doing so will not allow the use of the kernel
parameter "console=ttyUSB0,115200" as an example.

nozomi: Fix close on error
Nozomi assumes the close method isn't called if open errors. The tty layer
is different to other drives in this respect however. Pointed out by Denis J

serial: Make uart_port's ioport "unsigned long".
Otherwise the top 32-bits of the resource value get chopped
off on 64-bit systems, and the resulting I/O accesses go to
random places.
Thanks to testing and debugging by Josip Rodin, which helped
track this down.

audit: Handle embedded NUL in TTY input auditing
Data read from a TTY can contain an embedded NUL byte (e.g. after
pressing Ctrl-2, or sent to a PTY). After the previous patch, the data
would be logged only up to the first NUL.
This patch modifies the AUDIT_TTY record to always use the hexadecimal
format, which does not terminate at the first NUL byte. The vast
majority of recorded TTY input data will contain either ' ' or '\n', so
the hexadecimal format would have been used anyway.

ip2: avoid add_timer with pending timer
add_timer() is not supposed to be called when the timer is pending.
ip2 driver attempts to avoid that condition by setting and resetting
a flag (TimerOn) in timer function. But there is some gap between
add_timer() and setting TimerOn.
This patch fix this problem by using mod_timer() and remove TimerOn
which has been unnecessary by this change.

ip2: init/deinit cleanup
Cleanup of module_init/exit:
- mostly whitespace
- remove empty functions
- replace c++ comments
- remove useless prints (module loaded, unloaded)
- mark the calls as __exit and __init
- use break; and return; to save some indent levels after it
- note resource leakage

Char: merge ip2main and ip2base
It's pretty useless to have one setup() function separated along with
module_init() which only calls a function from ip2main anyway. Get rid
of ip2base.
