P.S.: To be sure the issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, the Linux kernel regression tracking bot: #regzbot report / #regzbot introduced aa69d6974185e9f7a552ba982540a38e34f69690 #regzbot title HID: i2c-hid: probe of i2c-XXX0001:00 failed with error -110 #regzbot ignore-activity -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr That page also explains what to do if mails like this annoy you.
