Subject: tpm xen: Remove bogus tpm_chip_unregister
From: Jason Gunthorpe <jgunthorpe@xxxxxxxxxxxxxxxxxxxx>
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")
