BTW we do have that taken care. spi_mem_adjust_op_size will adjust the transfer size according to max_transfer/message_size if no custom adjust_op_size hook is defined in the driver. If a custom adjust_op_size is defined, the driver adjusts the transfer size for it's exec_op hook. The size limit between exec_op and transfer_one_message can be different. (this spi-mtk-nor is an example of that.) -- Regards, Chuanhong Guo
