[PATCH AUTOSEL 4.9 04/12] HID: multitouch: Fix Iiyama ProLite T1931SAW (0eef:0001 again!)

[Sasha Levin]

From: Ondrej Zary <linux@xxxxxxx>

[ Upstream commit 32bea35746097985c48cec836d5f557a3b66b60a ]

Iiyama ProLite T1931SAW does not work with Linux - input devices are
created but cursor does not move.

It has the infamous 0eef:0001 ID which has been reused for various
devices before.

It seems to require export_all_inputs = true.

Hopefully there are no HID devices using this ID that will break.
It should not break non-HID devices (handled by usbtouchscreen).
