From aef3ad103a686f21b746977d4ed21cc1af36f589 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Sun, 13 Aug 2017 17:47:42 +0300 Subject: serial: core: remove unneeded 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.
