From f21ec3d2d46e5f2ffc06f31fe2704fdcea7a58f3 Mon Sep 17 00:00:00 2001 From: Huang Shijie Date: Wed, 22 Aug 2012 22:13:36 -0400 Subject: serial: add a new helper function In most of the time, the driver needs to check if the cts flow control is enabled. But now, the driver checks the ASYNC_CTS_FLOW flag manually, which is not a grace way. So add a new wraper function to make the code tidy and clean.
