3.0-stable review patch. If anyone has any objections, please let us know.
------------------ From: Stephen Warren <[email protected]> commit 5568181f188ae9485a0cdbea5ea48f63d186a298 upstream. Commit 4539c24fe4f92c09ee668ef959d3e8180df619b9 "tty/serial: Add explicit PORT_TEGRA type" introduced separate flags describing the need for IER bits UUE and RTOIE. Both bits are required for the XSCALE port type. While that patch updated uart_config[] as required, the auto-probing code wasn't updated to set the RTOIE flag when an XSCALE port type was detected. This caused such ports to stop working. This patch rectifies that.
