>From a code-generation standpoint, this is obiously correct, and probably
the compiler removes that omap_readw() already. But, to be honest, I'm not
perfectly sure on what the device expects -- and whether it's required to
write back the control register (or parts of it). Does anyone still have the
hardware (or specs)? If not, I'm tempted to apply this patch on the basis
that the compiler might remove that omap_readw() anyway.
