From 702131e2a393b45174be326f1dbe20b658b4f157 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Thu, 5 Mar 2015 18:25:10 +0100 Subject: bcma: move PCI IRQ control function to host specific code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This function isn't really related to any bus core. It touches PCI device config registers only, so move it to the (PCI) host file.
