Subject: serial: sh-sci: Use dev_dbg() to log an error message
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=51b31f1c6bbb3e741c930a71af8f0bcd4e5d4ded;p=openwrt%2Fstaging%2Fblogic.git

serial: sh-sci: Use dev_dbg() to log an error message

Since the driver cannot return from overrun error if characters
are output during overrun process, use dev_dbg() instead of
dev_notice() to log the error message of overrun in syslog.

Based on a patch by Hisashi Nakamura.
