Subject: seeing some junk characters on boot console with v4.9-rc1-3-g14155ca

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"
