Subject: [PATCH 4.4 56/60] tpm xen: Remove bogus tpm_chip_unregister

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jason Gunthorpe <jgunthorpe@...idianresearch.com>

commit 1f0f30e404b3d8f4597a2d9b77fba55452f8fd0e upstream.

tpm_chip_unregister can only be called after tpm_chip_register.
devm manages the allocation so no unwind is needed here.

Fixes: afb5abc262e96 ("tpm: two-phase chip management functions")
