From 44c6cf67c325245b4d78915fff4a0ade2b2bec45 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Sat, 24 Nov 2018 17:53:17 +0100 Subject: soc/intel/apl/acpi: Do not report 8259 PICs The IRQ tables don't support this path, so we shouldn't report presence of the legacy PICs. As the _PIC method is optional and we ignore the passed parameter anyway, drop it.
