From 711e5b4520986380700e6f095608021cf087170e Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Thu, 7 Feb 2013 14:58:35 +0100 Subject: asm-generic: io: Fix ioread16/32be and iowrite16/32be Fix ioreadXXbe and iowriteXXbe functions which did additional little endian conversion on native big endian systems. Using be_to_cpu (cpu_to_be) conversions with __raw_read/write functions have resolved it.
