I don't mind taking this one as long as we have a (justifiable) user for it. I assume you're using this in your driver, so let's with this patch until you post your driver? Thanks!

It would be useful, for example, to save ioremap()ed 'io_base' address, when a platform-specific driver uses 'priv' in 'struct hwspinlock' for something different.
