Hi,
this is (again) a series of cleanup in tty. I am trying to rework tty+serial to avoid limitations of devices (so called NR_UART or tty_alloc_driver()'s first parameter). And the below popped up while crawling through the code. So this is only a prep cleanup.
- many tty flags are now enums
- many functions were improved for readability
- quite a few unused or old code dropped
In particular, the runtime behaviour of the kernel before and after the changes is supposed to be bug to bug compatible (except moxa's ioctl and ISA evils dropped). That is, noone should notice.
[v2]
- use serial_port_in/out() helpers in 26/30 (and not use serial_in/out())
- the last patch is new
