Since commit 1513ceee70f2 (\"spi: bcm2835: Drop\ndma_pending flag\") the TX and RX DMA transfers are unconditionally\ncanceled, leading to NULL pointer derefs if ctlr->dma_tx or\nctlr->dma_rx are not set.\n\nFix the NULL pointer deref by checking that ctlr->dma_tx and\nctlr->dma_rx are valid pointers before accessing them.",
