[PATCH 0/2] platform/x86: hp-wmi: HP OmniBook Ultra 14-kd0xxx (8EB4) fixes

[Samuel Wheeler via B4 Relay <devnull+swheel33.gmail.com@kernel.org>]

Two small hp-wmi changes for the HP OmniBook Ultra Laptop 14-kd0xxx
(board 8EB4, BIOS F.06, Panther Lake):

1. The thermal profile query returns status flags in its upper bytes,
   so reading the platform profile always fails with -EINVAL. Use only
   the low byte.
2. The laptop has the same battery charge mode interface as the
   Spectre 8C15/8C17. Add it to the charge_behaviour quirk list.

Both were tested on the laptop with the same code changes applied to the
hp-wmi of a 7.2.15-based distribution kernel. The patches themselves are
against pdx86 for-next and build there with W=1 without warnings;
checkpatch --strict is clean.

Patch 2 touches the same quirk table as the pending "platform/x86:
hp-wmi: Add OmniBook 7 14-fr0xxx to charge_behaviour quirks"
(https://lore.kernel.org/r/20261102155409.3061761-1-taranarmo@gmail.com),
so whichever is applied second will need a trivial rebase.

The ACPI analysis, the changes and these descriptions were prepared with
an AI coding assistant (Claude, by Anthropic), as described in each
patch. I reviewed them and ran the tests myself.
