However there is no code for this, instead the interrupt handler is a threaded handler and uses spi_sync() instead. Remove the bitrotted comment, though in actual fact the use case mentioned is a great use for spi_async() since it would cut down on latency handling the interrupt by saving us a context switch before we start SPI. This was previously implemented, it was removed in commit b534422b2d11 (Input: ad7877 - switch to using threaded IRQ) for code complexity reasons. It may be better to revert that commit instead.
