ACPI/IORT: Remove iort_node_match()

Lorenzo Pieralisi · wildea01 · commit 91e0bf81258c · 2017-06-15T11:41:37.000+01:00
Commit 316ca88 ("ACPI/IORT: Remove linker section for IORT entries probing") removed the linker section for IORT entries probing. Since those IORT entries were the only iort_node_match() interface users, the iort_node_match() became obsolete and can then be removed. Remove the ACPI IORT iort_node_match() interface from the kernel.
