This way you can avoid a context switch.
Just a guess.

hint may not deactivate the chip select after the transaction when cs_change

This is a driver for the Synopsys DesignWare SPI master. This driver was
tested with an SPI flash device (m25p32), and an SPI Ethernet interface
(enc28j60), using their mainline drivers. spidev was also tested with a custom
SPI device.
