4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lukas Wunner <lukas@xxxxxxxxx>
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.
