    Subject[PATCH AUTOSEL 5.15 25/68] HID: multitouch: Fix Iiyama ProLite T1931SAW (0eef:0001 again!)
    Date
    From: Ondrej Zary <linux@zary.sk>

    [ 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).
