I need to manually call spi_message_add_tail() to append messages. I suppose that such function is a bit weird and no wonder why it is not being used. struct spi_message_with_transfers might need to be properly declared so that users can populate the transfer array without manually moving pointers or having to redefine the type. -- Kind regards, Rodrigo Alencar
