No problem, I agree this is better--just wasn't sure what you meant initially.

That is true, but apparently nobody can think of a better solution
(including me :)) and this bug has been open for two years. Having to
rmmod in the corner case where the module gets loaded but no i8042 is
present seems a small price to pay for having the keyboard work
regardless of CONFIG_I8042=y or m. Right now, any distribution with
CONFIG_I8042=m has a non-functional keyboard on Hyper-V Gen2 VMs,
which is probably frustrating for (e.g.) Arch Linux users who find
themselves unable to type and thus can't install their distribution.
