2019-07-26crypto: ccree - account for TEE not ready to reportGilad Ben-Yossef1-1/+7
When ccree driver runs it checks the state of the Trusted Execution Environment CryptoCell driver before proceeding. We did not account for cases where the TEE side is not ready or not available at all. Fix it by only considering TEE error state after sync with the TEE side driver.
