Subject: [PATCH 1/2] Write shared touch initial status only once
Date: Tue, 15 Sep 2026 19:03:01 -0700 [thread overview]
Message-ID: <20260916020301.24188-1-ping.cheng@wacom.com> (raw)
From: Ping Cheng <ping.cheng@wacom.com>
To match the same logic as with other shared data during registeration,
use WRITE_ONCE for is_touch_on too.
