[PATCH v2 0/2] platform/x86: msi-wmi: Fix unknown wmi event messages on MSI Claw models

["Derek J. Clark" <derekjohn.clark@gmail.com>]

MSI Claw devices produce WMI events through the MSI WMI hotkeys GUID for
some of their buttons. When pressed, these cause spam in the kernel. The
Claws use a GUID already supported by msi-wmi, but use an
ACPI_TYPE_BUFFER instead of an ACPI_TYPE_INTEGER.

Patch 1 reformats msi_wmi_notify() to reduce nesting by using early
returns and a switch case in preparation for handling this new data
type.

Patch 2 adds known MSI Claw event keycodes to the keymap and support for
ACPI_TYPE_BUFFER.
