*	ACPI: pfr_telemetry: Fix info leak in pfrt_log_ioctl()	Dan Carpenter	2022-01-10	1	-0/+1
\| \| \| \| \| \| \| \| \| \|	The "data_info" struct is copied to the user. It has a 4 byte struct hole after the last struct member so we need to memset that to avoid copying uninitialized stack data to the user.

*	ACPI: Introduce Platform Firmware Runtime Telemetry driver	Chen Yu	2021-12-27	1	-0/+434
	This driver allows user space to fetch telemetry data from the firmware with the help of the Platform Firmware Runtime Telemetry interface. Both PFRU and PFRT are based on ACPI _DSM interfaces located under special device objects in the ACPI Namespace, but these interfaces are different from each other, so it is better to provide a separate driver from each of them, even though they share some common definitions and naming conventions.
