From 717f3bbab3c7628736ef738fdbf3d9a28578c26c Mon Sep 17 00:00:00 2001 From: Seth Bollinger Date: Tue, 25 Mar 2014 12:55:37 -0500 Subject: [PATCH] serial_core: Fix conditional start_tx on ring buffer not empty If the serial_core ring buffer empties just as the tty layer receives an XOFF, then start_tx will never be called when the tty layer receives an XON as the serial_core ring buffer is empty. This will possibly leave a few bytes trapped in the fifo for drivers that disable the transmitter when flow controlled.
