AFAIU, your previous comment was to move initialization of
spi_flash_read_message struct to spi_flash_read(). This would mean
sending long list of arguments to spi_flash_read() which needs to be
updated whenever an argument needs to be added/deleted (in future).
Instead passing around a struct would be much easier in case of
adding/removing parameters.
Please correct me if I misunderstood your comment?
