Subject: [PATCH 04/24] iwlegacy: use writeb,writel,readl directly
Date: Mon, 13 Feb 2012 11:23:11 +0100	[thread overview]
Message-ID: <1329128611-6815-5-git-send-email-sgruszka@redhat.com> (raw)
In-Reply-To: <1329128611-6815-1-git-send-email-sgruszka@redhat.com>

That change will save us some CPU cycles at run time. Having
port-based I/O seems to be not possible for PCIe devices.
