[PATCH 1/1] toshiba_acpi: Remove unneeded u32 variables from *setup_keyboard

[PATCH 1/1] toshiba_acpi: Remove unneeded u32 variables from *setup_keyboard

[Azael Avalos]

The function toshiba_acpi_setup_keyboard currently has two u32 variables
used to store the Hotkey Event Type and the result of the HCI_SYSTEM_EVENT
query.

This patch removes those two variables, as we already have a global
variable named "hotkey_event_type" and the result of the HCI_SYSTEM_EVENT
query can be checked directly from the function.

[PATCH 1/1] toshiba_acpi: Add 0x prefix to available_kbd_modes_show funtion

[Azael Avalos]

This patch adds the 0x prefix to the values printed by such function, the
values are already being printed in hex, but without the prefix, causing
confussion, even though the file under Documentation/ABI clearly states
that hey are hex values.

Simply add the 0x prefix to avoid such confussion.

[PATCH] platform/x86: Toshiba WMI Hotkey Driver

[Azael Avalos]

Toshiba laptops that feature WMI events for hotkeys were left unsupported
by the toshiba_acpi driver, however, commit a88bc06e5aec ("toshiba_acpi:
Avoid registering input device on WMI event laptops") added hardware
support for such laptops, but the hotkeys are not handled there.

This driver adds support for hotkey monitoring on certain Toshiba laptops
that manage the hotkeys via WMI events instead of the Toshiba
Configuration Interface (TCI).

The toshiba_acpi driver and this one can co-exist, as this only takes
care of hotkeys, while the propper takes care of hardware related stuff.

Currently the driver is under the EXPERIMENTAL flag, as the keymap
and the notify function are incomplete (due to lack of hardware to test).

Ahem.

Missing the brace at the end and wreaking havoc on the poor compiler!

Since this will print all the time, perhaps a pr_dbg is more appropraite here...
