3.5-stable review patch. If anyone has any objections, please let me know.

From: Ian Abbott <abbotti@mev.co.uk>
commit e1878957b4676a17cf398f7f5723b365e9a2ca48 upstream.
Correct a direct dereference of I/O memory to use an appropriate I/O memory access function. Note that the pointer being dereferenced is not currently tagged with `__iomem` but I plan to correct that for 3.7.
