6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Armin Wolf <W_Armin@xxxxxx>
[ Upstream commit a54da9df75cd1b4b5028f6c60f9a211532680585 ]
The BIOS can choose to return no event data in response to a
WMI event, so the ACPI object passed to the WMI notify handler
can be NULL.
Check for such a situation and ignore the event in such a case.
Fixes: 23902f98f8d4 ("hwmon: add HP WMI Sensors driver")
