From 97f2c4289c591c2f24fb4a4cc03d78a0bef93187 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Mon, 19 Aug 2013 20:14:14 +0530 Subject: [PATCH] tty: serial: lpc32xx_hs: don't call tty_flip_buffer_push() twice serial_lpc32xx_interrupt() calls __serial_lpc32xx_rx() first and then tty_flip_buffer_push() immediately after that. But last statement of __serial_lpc32xx_rx() already called tty_flip_buffer_push().. So, probably its not required to be called twice. Lets remove one of them.
