Dear Maintainer,


   * What led up to the situation?
        Elan_i2c driver not working
        "elan_i2c 6-0015: failed to get resolution: -71"
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
        Ussing kernel parameter psmouse.elantech_smbus=0 works
   * What was the outcome of this action?
        The touchpad worked correctly
   * What outcome did you expect instead?
        Nothing

Is there any progress on this issue? My ELAN touchpad (Acer Aspire 7) is not
working either with linux-image-5.4.0-1-amd64 and linux-image-5.4.0-2-amd64
(have not tested linux-image-5.4.0-3-amd64 yet). It works with linux-image-
5.3.0-1-amd64.

Regards, Daniel

X-Debbugs-Cc: omarpurataf@gmail.com

Also latest kernel update in Debian testing (5.10.26-1) proved to have some regressions
with these elantech touchpads. When it stops working dmesg reports "IRQ triggeres but there's not data"
also trying to restart or reload the device using modprobe doesn't work.

Kernel reports:
i2c_hid i2c-ELAN2204:00: failed to reset device.
i2c_hid i2c-ELAN2204:00: can't hid device: -61
i2c_hid: probe of i2c.ELAN2204:00 failed with error -61

Haven't found anything of use in the kernel bugzilla, id be happy to test patches if the
maintainer needs help with this issue :)
