On certain Snapdragon processors, the crypto engine clocks are enabled by
default by security firmware and the driver need not/ should not handle the
clocks. Make acquiring of all the clocks optional in crypto enginer driver

typo, s/enginer/engine/

so that the driver intializes properly even if no clocks are specified in

typo, s/intializes/initializes/
