tpm: two-phase chip management functions
tpm_register_hardware() and tpm_remove_hardware() are called often
before initializing the device. The problem is that the device might
not be fully initialized when it comes visible to the user space.
This patch resolves the issue by diving initialization into two
parts:
- tpmm_chip_alloc() creates struct tpm_chip.
- tpm_chip_register() sets up the character device and sysfs
attributes.
The framework takes care of freeing struct tpm_chip by using the devres
API. The broken release callback has been wiped. ACPI drivers do not
ever get this callback.
Regards to Jason Gunthorpe for carefully reviewing this part of the
code.
