From d89e36d8df547fde2beaea82211954868da2282d Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Thu, 19 Oct 2006 14:21:47 +0100 Subject: [PATCH] [MIPS] Fix iounmap argument to const volatile. With the existing prototype the following code: const void __iomem *io = ioremap(); x = readb(io); iounmap(io); did result in a warning.
