From 661b0df8489a35da4ee8acaaf43f204a913ccfc9 Mon Sep 17 00:00:00 2001 From: Alexander Shishkin Date: Wed, 23 Aug 2017 09:47:19 +0300 Subject: intel_th: Pick up irq number from resources Platform devices pass their IRQs around as resources, so as a convenience for the glue layer code, allow them pass the IRQ to the core driver in the resources array.
