Hello folks, I'm currently working on some cleanups in drivers/tty/serial. There're several cases where new helpers, like devm_platform_ioremap_resource can be used, other places can use devm_ioremap_resource() for a bit cleaner code. Another topic here is using struct resource, instead of separate fields (BTW: struct uart_port->mapsize doesn't seem to be used consequently): in struct uart_port, I'm adding a struct resource field for holding the port's iomem range, and helpers for it. Then, I'm step by step patching the individual drivers to use that, instead of the old fields, directly. For now, this all is early, untested and not yet meant for mainline. I'd just like to have your oppions on my approach. What do you think about it ? thx --mtx
