Thank you, Takashi!  I installed this on the machine in question last
Saturday, but we did not encounter this issue since then.

(I.e., we did "lose" trackpad+touchscreen again, alas with a different
failure mode and without the i2c error message in the log.)

This notebook usually is a friend's, not mine, and her see her about
once a week and asked her to note down time and date of any issues and
will study the logs regularly.  Would it make sense to still proceed
upstream, or do you want to wait for a repeat occurrence?  (It is not
deterministic.)
