Jonathan Singer f4a31a428d platform/x86: hp-wmi: Add HP Envy special key support Previously, some support for certain keys on the HP keyboard has been added already in commit `3ee5447b20` ("platform/x86: hp-wmi: Handle Omen Key event"), however this as tested did not allow even the fn+esc key on my HP Envy which uses the same keycode on my HP Envy x360 laptop to work --the keycode rather than being passed in as a separate int from WMI, was being passed in as the event_data for the HPWMI_OMEN_KEY event. This patch, as tested was able to properly get the keycode for fn+esc, and for fn+f12 which is supposed to be a programmable key according to HP's keyboard diagram and is thus mapped to KEY_PROG2. The fn+f8 key combination (mute microphone) was a standard HPWMI_BEZEL_BUTTON key, however it did not previously have an entry in the sparse keymap. This patch preserves the original HPWMI_OMEN_KEY behavior for laptops that use it by only taking the keycode from the event_data only when the event_data is nonzero.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
