Subject: tpm xen: Remove bogus tpm_chip_unregister
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1f0f30e404b3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

tpm xen: Remove bogus tpm_chip_unregister

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