commit 29bdedfd9cf40e59456110ca417a8cb672ac9b92 upstream.
Commit e82b0b382845 ("spi: bcm2835: Fix race on DMA termination") broke the build with COMPILE_TEST=y on arches whose cmpxchg() requires 32-bit operands (xtensa, older arm ISAs).
Fix by changing the dma_pending flag's type from bool to unsigned int.
