[PATCH 4.9 005/103] tmp: use pdev for parent device in tpm_chip_alloc

[Greg Kroah-Hartman]

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

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

From: Winkler, Tomas <tomas.winkler@xxxxxxxxx>

commit 2998b02b2fb58f36ccbc318b00513174e9947d8e upstream.

The tpm stack uses pdev name convention for the parent device.
Fix that also in tpm_chip_alloc().

Fixes: 3897cd9c8d1d ("tpm: Split out the devm stuff from tpmm_chip_alloc")'
