From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ravi Chandra Sadineni Subject: [PATCH] i8042: Increment wakeup_count for the respective port. Date: Fri, 1 Jun 2018 11:00:53 -0700 Message-ID: <20180601180053.120202-1-ravisadineni@chromium.org> Return-path: 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 i8042 port was a potential wake reason for the last resume.
