Subject: [PATCH 055/122] serial: sh-sci: Fix minimal rx_timeout value
Commit "serial: sh-sci: use hrtimer for receive timeout"
breaks rx_timeout limit check. It used to be calculated
in jiffies and the minimal value was msecs_to_jiffies(20).
Since rx_timeout is now measured in uS, the minimal value
should be 20000 instead of 20.
