Novo key is the Lenovo define key on every ideapads, which has two
definition. Long press and short click. Driver will report
KEY_PROG1 on short click and KEY_PROG2 when long press.
On pre-install OS for ideapads there are application waiting for
the event and there is no such application for Linux yet, so I
think to report KEY_PROG is fine in anyway.
Also change the scancode from hex to decimal because they are
related to vpc bit in notify function which is in decimal.

This patch depends on the "Platform: Brightness quirk for samsung
laptop driver" patch from Jason Stubbs. This patch adds a check for an
initial brightness level of 0; if the level is 0, this patch changes
the brightness level to 1 before the driver attempts to detect the
brightness quirk.
The Samsung N150 netbook experiences the brightness quirk. Without
Jason's patch, the only brightness levels available on the N150 are 0,
1, and 8. This patch ensures that, when the initial brightness level
is 0, the samsang-laptop driver detects the brightness quirk on the
N150, thereby making brightness levels 0 through 8 available.

touchpad LED, 2 means turn it off.
BTW, I add dell_quirks to white list those machines that supports this
behavior, so that the code won't affect those who don't have a touchpad LED
machine.

Event 0x82 is emitted whenever a backlight event happens (brightness
change, backlight on/off). For instance, when display is switched
off after a timeout, event 0x82 is emitted, and along with it a keypress
which switches the display back on again.
This patch adds 0x82 to the event ignore list so that the display stays
off when it is automatically switched off.

On some Samsung laptops the brightness regulation works slightly different.
All SABI commands except for set_brightness work as expected. The behaviour
of set_brightness is as follows:
- Setting a new brightness will only step one level toward the new brightness
level. For example, setting a level of 5 when the current level is 2 will
result in a brightness level of 3.
- A spurious KEY_BRIGHTNESS_UP or KEY_BRIGHTNESS_DOWN event is also generated
along with the change in brightness.
- Neither of the above two issues occur when changing from/to brightness
level 0.
This patch adds detection and a non-intrusive workaround for the above issues.

The min_brightness value of the sabi_config is incorrectly used in brightness
calculations. For the config where min_brightness = 1 and max_brightness = 8,
the user visible range should be 0 to 7 with hardware being set in the range
of 1 to 8. What is actually happening is that the user visible range is 0 to
8 with hardware being set in the range of -1 to 7.
This patch fixes the above issue as well as a miscalculation that would occur
in the case of min_brightness > 1.
