Subject: [RFC v1 24/28] x86, irq: Kill unused alloc_irq_and_cfg_at()
Date: Fri, 26 Sep 2014 22:57:54 +0800 [thread overview]
Message-ID: <1411743478-31435-25-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1411743478-31435-1-git-send-email-jiang.liu@linux.intel.com>
There's no caller of alloc_irq_and_cfg_at() anymore, so kill it.
