Message-ID: <20190816082952.17985-2-jiada_wang@mentor.com>
Date: Fri, 16 Aug 2019 17:28:50 +0900
From: Jiada Wang <jiada_wang@...tor.com>
To: <nick@...anahar.org>, <dmitry.torokhov@...il.com>
CC: <linux-input@...r.kernel.org>, <linux-kernel@...r.kernel.org>,
<jiada_wang@...tor.com>, <george_davis@...tor.com>
Subject: [PATCH v1 01/63] Input: introduce input_mt_report_slot_inactive
input_mt_report_slot_state() ignores the tool when the slot is closed.
which has caused a bit of confusion.
This patch introduces input_mt_report_slot_inactive() to report slot
inactive state.
replaces all input_mt_report_slot_state() with input_mt_report_slot_inactive()
in case of close of slot, also some other related changes.
