[ 072/184] staging: comedi: jr3_pci: fix iomem dereference

From: Willy Tarreau
Date: Tue Jun 04 2013 - 18:47:57 EST

2.6.32-longterm review patch. If anyone has any objections, please let me know.


From: Ian Abbott <abbotti@xxxxxxxxx>

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.
