From 9893c80d81587ac25d8ea4a82651371b54e7df35 Mon Sep 17 00:00:00 2001 From: Peter Crosthwaite Date: Tue, 12 Feb 2013 11:29:31 +1000 Subject: [PATCH] cadance_uart: Accept input after rx FIFO pop The device returns false from the can receive function when the FIFO is full. This means the device should check for buffered input whenever a byte is popped from the FIFO.
