An exiting session leader can hang if a foreground process is
blocking for line discipline i/o, eg. in n_tty_read(). This happens
because the blocking reader is holding an ldisc reference (indicating
the line discipline is in-use) which prevents __tty_hangup() from
recycling the line discipline. Although waiters are woken before
attempting to gain exclusive access for changing the ldisc, the
blocking reader in this case will not exit the i/o loop since it
has not yet received SIGHUP (because it has not been sent).
Instead, perform signalling first, then recycle the line discipline.
Fixes:

When the session leader is exiting, signal the foreground group
processes as part of the hangup sequence, instead of after the
hangup is complete. This prepares for hanging up the
line discipline _after_ signalling processes which
may be blocking on ldisc i/o.
Parameterize __tty_hangup() to distinguish between when the
session leader is exiting and all other hangups; signal the
foreground group after signalling the session leader and its
process group, which preserves the original signal order.

The code in 8250.c for detecting ARM/XScale UARTs says:
* Try writing and reading the UART_IER_UUE bit (b6).
* If it works, this is probably one of the Xscale platform's
* internal UARTs.
If the above passes, it then goes on to:
* It's an Xscale.
* We'll leave the UART_IER_UUE bit set to 1 (enabled).
However, the CH352 uses the UART_IER_UUE as the LOWPOWER function,
so it is readable and writable. According to the datasheet:
"LOWPOWER:When the bit is 1, close the internal benchmark
clock of serial port to set into low-power status.
So it essentially gets mis-detected as Xscale, and gets
powered down in the process. The device in question where
this was seen is listed by lspci as:
Serial controller: Device 4348:3253 (rev 10) (prog-if 02 [16550])
Re-using the 353 quirk which just sets flags to fixed and type
to 16550 is suitable for fixing the 352 as well.

When sending between processes, we always schedule a work item. Our work info
struct has the message embedded in the middle, which means that we end up
overwriting subsequent fields when we copy the (variable-length) message into
it. Move it to the end of the struct.

This is small fixes against 3.9-rc2.
Fix to max77693 extcon driver:
- Set default value of MUIC register to bring up it.
Fix to max8997 extcon driver:
- Fix null pointer error duing probe when platform data
isn't used.

Introduce the module_pcmcia_driver() macro which is a convenience macro
for pcmcia driver modules. It is intended to be used by pcmcia drivers
with init/exit sections that do nothing but register/unregister the
pcmcia driver.

One function is ipack_device_init(). If it fails, the caller should execute
ipack_put_device().
The second function is ipack_device_add that only adds the device. If
it fails, the caller should execute ipack_put_device().
Then the device is removed with refcount = 0, as device_register() kernel
documentation says.
ipack_device_del() is added to remove the device.
