From 05ab3014636ff60a319d37cdf37dca594b015eec Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 9 May 2005 23:21:59 +0100 Subject: [PATCH] Serial: Add uart_insert_char() Add uart_insert_char(), which handles inserting characters into the flip buffer. This helper function handles the correct semantics for handling overrun in addition to inserting normal characters.
