Subject: [PATCH 3/5] USB: serial: cp210x: add support for TIOCGICOUNT
Date: Mon, 13 Jul 2020 12:55:15 +0200 [thread overview]
Message-ID: <20200713105517.27796-4-johan@kernel.org> (raw)
In-Reply-To: <20200713105517.27796-1-johan@kernel.org>
Enable TIOCGICOUNT to allow reading out the (unused) interrupt counters
and error statistics.
Note that modem-status events are currently left unimplemented as they
appear to be buffered on at least CP2102 and therefore cannot be used to
implement TIOCMIWAIT.
