[PATCH] Input: i8042 - Fix console keyboard support on Gen2 Hyper-V VMs

[Mark Laws]

Hi,

Please keep me Cc:ed in any replies as I'm not on these lists.

Description of the fix is in the commit message for the patch.

Discussion:

Given that most distributions were already statically linking i8042.c,
having it not unload even if there is no i8042 device seems a better fix
than the alternatives:

a) requiring users build a kernel with CONFIG_SERIO_I8042=y;
b) duplicating the needed bits from atkbd.c in hyperv-keyboard, or;
c) this patch, but with a "stay_resident=1" option to enable the
   workaround.  Detecting presence of Hyper-V could be handled by udev,
   which would pass this option, but every distribution would need to
   fix their rules (certainly we don't want to check for Hyper-V in
   i8042.c)
