From mboxrd@z Thu Jan 1 00:00:00 1970 From: Peter Hurley Subject: [PATCH 07/26] serial: mpc52xx: Use default serial core x_char handler Date: Tue, 2 Sep 2014 17:39:16 -0400 Message-ID: <1409693975-1028-8-git-send-email-peter@hurleysoftware.com> References: <1409693975-1028-1-git-send-email-peter@hurleysoftware.com> Return-path: In-Reply-To: <1409693975-1028-1-git-send-email-peter@hurleysoftware.com> Sender: linux-kernel-owner@vger.kernel.org To: Greg Kroah-Hartman Cc: Jiri Slaby , One Thousand Gnomes , linux-serial@vger.kernel.org, linux-kernel@vger.kernel.org, Peter Hurley List-Id: linux-serial@vger.kernel.org mpc52xx_uart_send_xchar() is _identical_ to the default serial core x_char handling behavior in uart_send_xchar(). Remove mpc52xx_uart_send_xchar().
