*	ACPI: configfs: Unload SSDT on configfs entry removal	Jan Kiszka	2017-06-22	1	-1/+19
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Call directly into acpica to load a table to obtain its index on return. We choose the direct call of acpica internal functions to avoid having to modify its API which is used outside of Linux as well. Use that index to unload the table again when the corresponding directory in configfs gets removed. This allows to change SSDTs without rebooting the system. It also allows to destroy devices again that a dynamically loaded SSDT created. This is widely similar to the DT overlay behavior.

*	ACPI: Rename configfs.c to acpi_configfs.c to prevent link error	Mika Westerberg	2016-07-11	1	-0/+267
	If we compile ACPI configfs.c as module it will confuse the linker as it hides symbols from the actual configfs: Kernel: arch/x86/boot/bzImage is ready (#1236) MODPOST 5739 modules ERROR: "configfs_unregister_subsystem" [samples/configfs/configfs_sample.ko] undefined!
