Subject: [PATCH 05/16] tty: serial: 8250_core: remove UART_IER_RDI in serial8250_stop_rx()
Date: Wed, 10 Sep 2014 21:30:00 +0200 [thread overview]
Message-ID: <1410377411-26656-6-git-send-email-bigeasy@linutronix.de> (raw)
In-Reply-To: <1410377411-26656-1-git-send-email-bigeasy@linutronix.de>
serial8250_do_startup() adds UART_IER_RDI and UART_IER_RLSI to ier.
serial8250_stop_rx() should remove both.
This is what the serial-omap driver has been doing and is now moved to
the 8250-core since it does no look to be *that* omap specific.
