[v2,0/2] Improve error handling during INIT_EX file initialization

Message

Jacky Li Aug. 16, 2022, 7:32 p.m. UTC

Currently the PSP initialization fails when the INIT_EX file is missing
or invalid, while the initialization continues when the OS fails to
write the INIT_EX file. This series handles both cases in a more robust
way by resolving the file read error as well as throwing the write error
to the caller.
---
Changelog since v1:
- refactor around __sev_init_ex_locked() and fix format.

Jacky Li (2):
  crypto: ccp - Initialize PSP when reading psp data file failed
  crypto: ccp - Fail the PSP initialization when writing psp data file
    failed
