In stm32_hash_write_ctrl() that set up all the algorithm properties this flag seems to mean "initialized the control register", as it sets the flag after initializing the register and then does not write it again if the flag is set. I wonder if this is in line with the crypto driver expectations of that flag. I am wondering because at the end stm32_hash_dma_send() you set this flag, and that function calls stm32_hash_write_ctrl() first thing it does which will set the flag unless it was set already.
