Hi all,

Here are more serial console rebind improvments for 8250_omap. Turns out
there have been some life cycle issues in the driver for quite a while.
The issues rebinding the driver have certainly made debugging serial core
runtime PM changes a bit harder..

Probably only the first patch is needed as a fix for the stable kernels.

Not sure if folks have been hitting the other issues so far. These might
issues only if device tree overlays are being used for serial ports, and
I'm not aware of such cases so far with the mainline kernel.

Regards,

Tony
