From 16f404e3666718917b2541503240cf8430aa49ff Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Tue, 2 Sep 2014 17:39:16 -0400 Subject: [PATCH] serial: mpc52xx: Use default serial core x_char handler mpc52xx_uart_send_xchar() is _identical_ to the default serial core x_char handling behavior in uart_send_xchar(). Remove mpc52xx_uart_send_xchar().
