From mboxrd@z Thu Jan 1 00:00:00 1970 From: Kevin Cernekee 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 Message-ID: <1415342669-30640-9-git-send-email-cernekee@gmail.com> References: <1415342669-30640-1-git-send-email-cernekee@gmail.com> Return-path: In-Reply-To: <1415342669-30640-1-git-send-email-cernekee@gmail.com> Sender: linux-mips-bounce@linux-mips.org Errors-to: linux-mips-bounce@linux-mips.org List-help: List-unsubscribe: List-software: Ecartis version 1.0.0 List-subscribe: List-owner: List-post: List-archive: To: tglx@linutronix.de, jason@lakedaemon.net, linux-sh@vger.kernel.org Cc: arnd@arndb.de, f.fainelli@gmail.com, ralf@linux-mips.org, sergei.shtylyov@cogentembedded.com, linux-kernel@vger.kernel.org, devicetree@vger.kernel.org, mbizon@freebox.fr, jogo@openwrt.org, linux-mips@linux-mips.org List-Id: devicetree@vger.kernel.org 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.
