Subject: [PATCH AUTOSEL 5.4 30/49] HID: quirks: Add HID_QUIRK_NO_INIT_REPORTS quirk for Dell K12A keyboard-dock
Date: Thu, 14 May 2020 14:52:51 -0400 [thread overview]
Message-ID: <20200514185311.20294-30-sashal@kernel.org> (raw)
In-Reply-To: <20200514185311.20294-1-sashal@kernel.org>
From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit 1e189f267015a098bdcb82cc652d13fbf2203fa0 ]
Add a HID_QUIRK_NO_INIT_REPORTS quirk for the Dell K12A keyboard-dock,
which can be used with various Dell Venue 11 models.
Without this quirk the keyboard/touchpad combo works fine when connected
at boot, but when hotplugged 9 out of 10 times it will not work properly.
Adding the quirk fixes this.
