ACPI: scan: initialize local variable to avoid garbage being returned
In the unlikely event that there are no callback calls made in
acpi_walk_dep_device_list(), local variable ret will be returned as
an uninitialized value.
Clean up static analysis warnings by ensuring ret is initialized.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: a9e10e587304 ("ACPI: scan: Extend acpi_walk_dep_device_list()")
