None of these files are actually using any __init type directives

The driver can't deal with two entries its keymap having the same keycode.
When this happens it will get confused about whether the key is down or up
and will cause some screwy behavior.

We need to have two entries for KEY_BACKSLASH to handle US and UK
keyboards. Specifically:
* On the US keyboard the backslash key (above enter) is r3 c11 and is
  supposed to be reported as BACKSLASH.
* On the UK keyboard the # key (left of enter) is r4 c10 and is
  supposed to be reported as BACKSLASH.
* On the UK keyboard the \ key (left of Z) is r2 c7 and is supposed to
  be reported as KEY_102ND.

Note that both keyboards (US and UK) have only one physical backslash
key so the constraint that each physical key should have its own keycode
still stands.

The current assumption in the elantech driver that hw version 3 touchpads
are never clickpads and hw version 4 touchpads are always clickpads is
wrong.

There are several bug reports for this, ie:
https://bugzilla.redhat.com/show_bug.cgi?id=1030802
http://superuser.com/questions/619582/right-elantech-touchpad-button-not-working-in-linux

I've spend a couple of hours wading through various bugzillas, launchpads
and forum posts to create a list of fw-versions and capabilities for
different laptop models to find a good method to differentiate between
clickpads and versions with separate hardware buttons.

Which shows that a device being a clickpad is reliable indicated by bit 12
being set in the fw_version. I've included the gathered list inside the
driver, so that we've this info at hand if we need to revisit this later.

For NUMA systems, initializing the blk-mq layer and using per node hctx.
We initialize submit queues to 1, while blk-mq nr_hw_queues is

This makes the null_init_hctx function overwrite memory outside of what
it allocated.  In my case it lead to writing garbage into struct
