[GIT PULL] libata changes for v4.17-rc1

[Tejun Heo]

Hello, Linus.

Nothing too interesting.  The biggest change is refcnting fix for
ata_host - the bug is recent and can only be triggered on controller
hotplug, so very few are hitting it.  There also are a number of
trivial license / error message changes and some hardware specific
changes.

Thanks.

People hotplug ATA _controllers_?   :-O

As opposed to just the disks a'la eSATA?

I knew of pcmcia ata cards ("People still do pcmcia?"), but didn't
realize it really happened elsewhere.

Regardless, pulled.

Heh, yeah, it's surprising.  IIUC, it's people trying pcie hotplug (I
don't know whether they try physically) on SAS controllers on fancy
machines.

Thanks.
