From 9c3438ed215adba7025268ee1f0b6f7a2af12316 Mon Sep 17 00:00:00 2001
From: Ian Molton <ian@mnementh.co.uk>
Date: Tue, 19 Dec 2017 13:47:14 +0100
Subject: [PATCH] brcmfmac: Clean up interrupt macros
Make it more obvious that this code acually enables interrupts, and
provide nice definitions for the bits in the register.
