      Input: imx_sc_key - correct SCU message structure to avoid stack corruption · dffe969a
      Anson Huang authored
      The SCU message's data field used for receiving response data from SCU
      should be 32-bit width, as SCU will send back 32-bit width data.
      
      This solves kernel panic when CONFIG_CC_HAVE_STACKPROTECTOR_SYSREG is
      enabled.
