platform/x86: thinkpad_acpi: Switch to using sparse-keymap helpers
Switch the hotkey keymap handling over to the sparse-keymap helpers, there should be no functional changes from this. Note all the mappings to KEY_UNKNOWN are removed since that is the default behavior of sparse_keymap_report_event() for unknown scancodes. Also drop the big comment about making changes to the keymaps since the contents of that comment are mostly obsolete.

|
||||
* knowledge on the IBM and Lenovo ThinkPad firmware for
|
||||
* the various ThinkPad models. The driver behaves

* differently for KEY_RESERVED: such keys have their
|
||||
* hot key mask *unset* in mask_recommended, and also
|
||||
* in the initial hot key mask programmed into the
|
||||
* firmware at driver load time, which means the firm-
|
||||
* ware may react very differently if you change them to
|
||||
* something else;
|
||||
*
|
||||
* 2. You must be subscribed to the linux-thinkpad and
|
||||
* ibm-acpi-devel mailing lists, and you should read the
|
||||
* list archives since 2007 if you want to change the
|
||||
* keymaps. This requirement exists so that you will
|
||||
* know the past history of problems with the thinkpad-
|
||||
* acpi driver keymaps, and also that you will be
|
||||
* listening to any bug reports;
|
||||
*
|
||||
* 3. Do not send thinkpad-acpi specific patches directly to
|
||||
* for merging, *ever*. Send them to the linux-acpi
|
||||
* mailinglist for comments. Merging is to be done only
|
||||
* through acpi-test and the ACPI maintainer.
|
||||
*
|
||||
* If the above is too much to ask, don't change the keymap.

* Ask the thinkpad-acpi maintainer to do it, instead.
