[PATCH 05/11] irqchip: bcm7120-l2: Make sure all register accesses use base+offset

From: Kevin Cernekee
Date: Wed Oct 29 2014 - 00:01:34 EST


A couple of accesses to IRQEN (base+0x00) just used "base" directly, so
they would break if IRQEN ever became nonzero. Make sure that all
reads/writes specify the register offset constant.
