Hi

I am seeing some junk characters on uart boot console on DRA72x platform
[1] and even on other TI platforms, did a bisect and found the commit
"761ed4a94582" broke it first.

By reverting below two commit, I don't see the issue logs [2].

761ed4a94582 "tty:serial_core: convert uart_close to use tty_port_close"
a5a2b13074fd "serial: core: fix potential NULL pointer dereference"

[1] - http://pastebin.ubuntu.com/23343431/
[2] - http://pastebin.ubuntu.com/23343435/

Regards

Can you test with the patch titled "tty: serial_core: Fix serial
console crash on port shutdown"[1]? It may be disabling the console
when it shouldn't.
