Subject: [PATCH v7 01/48] Input: introduce input_mt_report_slot_inactive
Date: Wed, 12 Feb 2020 00:41:31 -0800	[thread overview]
Message-ID: <20200212084218.32344-2-jiada_wang@mentor.com> (raw)
In-Reply-To: <20200212084218.32344-1-jiada_wang@mentor.com>

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.
