+/* Name: optee_msg_alloc
+ *
+ * Description:
+ * Allocate OP-TEE page-aligned memory for use as arguments to OP-TEE
+ * calls, large enough to fit `numparams` parameters. Initialize the
+ * buffer to 0, and set the `.num_params` field to the specified value.
+ *
+ * Use `optee_msg_free()` to free the memory returned.
+ *
+ * Parameters:
+ * priv - pointer to the driver's optee_priv_data struct
+ * numparams - the number of arguments to allocate shared memory for.
+ * Can be zero.
+ *
+ * Returned Values:
+ * On success, pointer to OP-TEE message arguments struct initialized
+ * to 0 except for `.num_params`, which is initialized to the specified
+ * number of parameters.
+ * On failure, NULL.
