From d88812a8d66617efdb41d787efca0907ccd98716 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 24 Jan 2022 08:14:28 +0100 Subject: [PATCH] serial: fsl_linflexuart: don't call uart_write_wakeup() twice linflex_txint() calls linflex_transmit_buffer() which calls uart_write_wakeup(). So there is no point to repeat it in linflex_txint() again -- remove it.
