There is a comment in the code saying it is needed, here is more
context:

static void bcm2835_data_irq(struct bcm2835_host *host, u32 intmask)
{
/* There are no dedicated data/space available interrupt
* status bits, so it is necessary to use the single shared
* data/space available FIFO status bits. It is therefore not
* an error to get here when there is no data transfer in
* progress.
*/
if (!host->data)
return;

bcm2835_check_data_error(host, intmask);

cheers,
Gerd
