[Qemu-devel] [PULL 1/5] acpi: verify file entries in bios_linker_loader_add_pointer()

["Michael S. Tsirkin" <mst@redhat.com>]

From: Liam Merwick <liam.merwick@oracle.com>

The callers to bios_linker_find_file() assert that the file entry returned
is not NULL, except for those in bios_linker_loader_add_pointer().  Add two
asserts in that case for completeness and to facilitate static code analysis.
