Subject: tmp: use pdev for parent device in tpm_chip_alloc
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")'
