Subject: [PATCH] locomo: drop special locomo_{read/write}l in favor of io{read/write}16
All the locomo registers are 16-bit ioremap'ed memory addresses.
Make the locomo drivers use generic purpose io routines: ioread16
and iowrite16 instead of directly accessing memory.
There are still a couple checkpatch warnings about lines exceeding
79 characters.
