Currently token address is printed using %p. This exposes the address of the token in dmesg and potentially leaks sensitive information to userspace. In this instance the address is being used as a unique identifier for the token, we can use the newly defined printk specifier %px for exactly this purpose. Use the new %px specifier to print a unique identifier for the token. Signed-off-by: Tobin C.
