Subject: sh: se7206: Handle non-SuperIO I/O ports.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=8f3dc1371efb5fd5f1dc02b2a01da589f2d220a0;p=deliverable%2Flinux.git

sh: se7206: Handle non-SuperIO I/O ports.

This fixes up the port calculation logic for non-SuperIO accesses,
before these were always matching the MRSHPC base, now just make
sure the original port is handed back if it's not in the I/O port
range.
