From 29d60981db522ce301e06e18d9edf8b31b233b89 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Sun, 13 Aug 2017 17:47:41 +0300 Subject: [PATCH] serial: stm32-usart: Avoid using irq_wake flag There is no need to duplicate a flag which IRQ core takes care of. Replace custom flag by IRQ core API that retrieves its state.
