Subject: [PATCH V4 08/14] irqchip: bcm7120-l2: Make sure all register accesses use base+offset
Date: Thu,  6 Nov 2014 22:44:23 -0800	[thread overview]
Message-ID: <1415342669-30640-9-git-send-email-cernekee@gmail.com> (raw)
In-Reply-To: <1415342669-30640-1-git-send-email-cernekee@gmail.com>

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.
