Subject: [Patch v6 4/7] leds: ledtrig-tty: change logging if get icount failed

Change the log level from info to warn, because there is something
wrong. That is more a warn message than an info message.

While we are at it, the device prefix is also changed, as this is the
led device and not the tty device that generates this message.
