Jerome Forissier 9584ce366c tee: optee: do not check memref size on return from Secure World ... [ Upstream commit c650b8dc7a ] When Secure World returns, it may have changed the size attribute of the memory references passed as [in/out] parameters. The GlobalPlatform TEE Internal Core API specification does not restrict the values that this size can take. In particular, Secure World may increase the value to be larger than the size of the input buffer to indicate that it needs more. Therefore, the size check in optee_from_msg_param() is incorrect and needs to be removed. This fixes a number of failed test cases in the GlobalPlatform TEE Initial Configuratiom Test Suite v2_0_0_0-2017_06_09 when OP-TEE is compiled without dynamic shared memory support (CFG_CORE_DYN_SHM=n).
