ACPI, APEI, HEST Fix the unsuitable usage of platform_data
platform_data in hest_parse_ghes() is used for saving the address of entry
information of erst_tab. When the device is failed to be added, platform_data
will be freed by platform_device_put(). But the value saved in platform_data
should not be freed here. If it is done, it will make system panic.
So I think platform_data should save the address of allocated memory
which saves entry information of erst_tab.
This patch fixed it and I confirmed it on x86_64 next-tree.
v2:
Transport the pointer of hest_hdr to platform_data using
platform_device_add_data()
