Subject: [PATCH v7 01/10] tpm: Get rid of chip->pdev
From: Jason Gunthorpe <jgunthorpe@...idianresearch.com>
This is a hold over from before the struct device conversion.
- All prints should be using &chip->dev, which is the Linux
standard. This changes prints to use tpm0 as the device name,
not the PnP/etc ID.
- The few places involving sysfs/modules that really do need the
parent just use chip->dev.parent instead
- We no longer need to get_device(pdev) in any places since it is no
longer used by any of the code. The kref on the parent is held
by the device core during device_add and dropped in device_del
