Subject: Input: adbhid - fix capslock key state after suspend

If the adbhid module parameter restore_capslock_events is used,
sometimes capslock will get stuck down after resuming.

My fix is to remember the capslock state before suspend and then
ignore the first 'caps lock key down' message after resume if the
capslock LED was on before suspending.

Subject: Input: adbhid - capslock and power button fix

If the adbhid module parameter restore_capslock_events is used,
pressing the power button may confuse the capslock state. This is
because the power button release scancode (0xff) is sometimes the same
as the capslock press/release scancode.

This fix adds yet another flag to track the state of the power button
so that it works independently of capslock.

Subject: Input: add support for SuperH MigoR touchscreen

This is V2 of the MigoR touch screen driver. The chip we interface to
is unfortunately a custom designed microcontroller speaking some
undocumented protocol over i2c.

The board specific code is expected to register this device as an i2c
chip using struct i2c_board_info [] and i2c_register_board_info().

[dtor@mail.ru: don't enable touchscreen if there are no users]

Subject: Input: i8042 - add Intel D845PESV to nopnp list

This patch introduces i8042_dmi_nopnp_table to make it possible to perform
DMI matches for systems that need 'i8042.nopnp' to work correctly, and
introduces such an entry for Intel D845PESV -- this system doesn't
detect PS2 mouse reliably without this option, as reported by Robert
Lewis.

[dtor@mail.ru - make it compile if CONFIG_PNP is off - reported
 by Randy Dunlap]

Subject: Input: atkbd - use ushort instead of uchar keymap

Since some of the keycodes defined in input.h have values greater
than 255 we should use unsigned shorts in keymaps.

From f2278f31d6feb9036eaa79f2e8abcce850420abd Mon Sep 17 00:00:00 2001
From: Adam Dawidowski <drake_ster@wp.pl>
Date: Mon, 2 Jun 2008 01:08:10 -0400
Subject: Input: fix force feedback upload issue in compat mode

Force feedback upload of effects through the event device (ioctl
EVIOCSFF) is not working in 32 bit applications running on 64-bit
kernel due to the fact that struct ff_effect contains a pointer,
resulting in the structure having different sizes in 64 and 32 bit
programs and causing difference in ioctl numbers.

[dtor@mail.ru: refactor to keep all ugliness in evdev]

Subject: Input: atkbd - fix HP 2133 not sending release event for video switch

Video switch key on HP 2133 doesn't send release event, so we
have to create workaround similar to what we do for Dell Latitude,
i.e. perform DMI match for the system and generate 'false' release
event ourselves, so that userspace doesn't think that the key is
stuck forever.

Subject: Input: yealink - reliably kill urbs

Yealink uses two URBs that submit each other. This arrangement
cannot be reliably killed with usb_kill_urb() alone, as there's
a window during which the wrong URB may be killed. The fix is
to introduce a flag.

[dtor@mail.ru: remove spinlock, flag alone should be enough]

Date: Mon, 14 Jul 2008 10:28:32 -0400
Subject: Input: add option to disable HP SDC driver

Add "no_hpsdc" kernel module option to the hp_sdc driver, so that
the driver can be instructed to not enable the HP SDC port.

This is useful on some older HPPA boxes with HIL keyboard
and HIL mouse where the new HP SDC HIL drivers don't work
yet. By disabling the new hp_sdc driver users are able to use
the older hilkbd driver instead.
