From 6915564dc5a8ab831a016e0cd0a8a3c68230287b Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 11 Sep 2020 14:59:35 +0200 Subject: ACPI: OSL: Change the type of acpi_os_map_generic_address() return value Modify acpi_os_map_generic_address() to return the pointer returned by acpi_os_map_iomem() which represents the logical address corresponding to the struct acpi_generic_address argument passed to it or NULL if that address cannot be obtained (for example, the argument does not represent an address in system memory or it could not be mapped by the OS). Among other things, that will allow the ACPI OS layer to pass the logical addresses of the FADT GPE blocks 0 and 1 to ACPICA going forward. Signed-off-by: Rafael J.
