Fix the following compilation failure with v3.2-rc1 by including module.h:

Input: i8042 - add HP Pavilion dv4s to 'notimeout' and 'nomux' blacklists

2011-11-05T07:03:21+00:00

Touchpad input doesn't work with newer HP Pavilion dv4 laptops due to bad i8042
timeout data.  Booting with i8042.notimeout and i8042.nomux successfully works
around the problem.

This patch adds the devices to the i8042 notimeout and nomux blacklists.

Input: serio_raw - fix memory leak when closing char device

2011-10-11T01:35:23+00:00

Apparently we never freed memory allocated when users open our char
devices nor removed old users from the list of connected clients.

Also unregister misc device immediately upon disconnecting the port
instead of waiting until last user drops off (refcounting in misc
device code will make sure needed pieces stay around while they
are needed) and make sure we are not holing holding serio_raw_mutex
when registering/unregistering misc device. This should fix potential
deadlock between serio_raw and misc device code uncovered by lockdep
and reported by Thomas Tuttle.

Input: serio_raw - kick clients when disconnecting port

2011-10-11T01:35:18+00:00

Send SIGIO/POLL_HUP and otherwise wake up waiters when corresponding serio
port is being disconnected. Also check if port is dead in serio_raw_poll
and signal POLLHUP|POLLERR.

This should speed up process of releasing dead devices by userspace
applications.

Input: serio_raw - explicitly mark disconnected ports as dead

2011-10-11T01:35:13+00:00

Instead of relying on setting serio_raw->serio to NULL upon disconnecting
ports mark them explicitly as "dead". Also take and carry reference to
underlying serio port to make sure it does not go away until we are done
with it.

This will ensure our reporting is consistent with the rest of the system.

Input: serio_raw - perform proper locking when adding clients to list

2011-10-11T01:34:55+00:00

Make sure we hold serio lock when adding clients to client list so that
we do not race with serio_raw_release() removing clients from the same
list.

Input: serio_raw - rename serio_raw_list to serio_raw_client

2011-10-11T01:34:52+00:00

'serio_raw_list' and 'list' names do not accurately represent their objects
and are extremely confusing when reading the code. Let's use better suited
names.
