Subject: staging: comedi: jr3_pci: fix iomem dereference
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=e1878957b4676a17cf398f7f5723b365e9a2ca48;p=openwrt%2Fstaging%2Fblogic.git

staging: comedi: jr3_pci: fix iomem dereference

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.
