Date: Fri, 1 Jun 2018 18:07:08 -0700 Message-ID: <20180602010708.152025-1-ravisadineni@chromium.org> References: <20180601180053.120202-1-ravisadineni@chromium.org> Return-path: In-Reply-To: <20180601180053.120202-1-ravisadineni@chromium.org> Sender: linux-kernel-owner@vger.kernel.org To: dmitry.torokhov@gmail.com, chenhong3@huawei.com, ravisadineni@chromium.org, ravisadineni@google.com, dtor@google.com Cc: tbroch@google.com, linux-kernel@vger.kernel.org, linux-input@vger.kernel.org, rajatja@google.com, bleung@google.com List-Id: linux-input@vger.kernel.org Call pm_wakeup_event on every irq. This should help us in identifying if keyboard was a potential wake reason for the last resume.
