HID: steam: Fix input device disappearing

2020-02-01T09:34:46+00:00

[ Upstream commit 20eee6e5af35d9586774e80b6e0b1850e7cc9899 ]

The `connected` value for wired devices was not properly initialized,
it must be set to `true` upon creation, because wired devices do not
generate connection events.

When a raw client (the Steam Client) uses the device, the input device
is destroyed. Then, when the raw client finishes, it must be recreated.
But since the `connected` variable was false this never happended.

drivers/hid/hid-multitouch.c: fix a possible null pointer access.

We previously assumed 'mt' could be null (see line 1002).

The following situation is similar, so add a judgement.

HID: asus: Ignore Asus vendor-page usage-code 0xff events

[ Upstream commit c07a0254c89e4bb69ca781cd488baa5b628e2754 ]

At least on a T100HA an Asus vendor-page usage-code 0xff event is send on
every suspend and again on resume, resulting in the following warning:

asus 0003:0B05:1807.0002: Unmapped Asus vendor usagepage code 0xff

being logged twice on every suspend/resume.

This commit silences the "Unmapped Asus vendor usagepage code ..."
warning for usage-code 0xff to avoid these warnings being logged.

HID: ite: Add USB id match for Acer SW5-012 keyboard dock

2020-02-01T09:34:40+00:00

[ Upstream commit 8f18eca9ebc57d6b150237033f6439242907e0ba ]

The Acer SW5-012 2-in-1 keyboard dock uses a Synaptics S91028 touchpad
which is connected to an ITE 8595 USB keyboard controller chip.

This keyboard has the same quirk for its rfkill / airplane mode hotkey as
other keyboards with the ITE 8595 chip, it only sends a single release
event when pressed and released, it never sends a press event.

This commit adds this keyboards USB id to the hid-ite id-table, fixing
the rfkill key not working on this keyboard.
