Subject[PATCH 4.4 55/88] spi: bcm2835: Unbreak the build of esoteric configs
4.4-stable review patch.  If anyone has any objections, please let me know.


From: Lukas Wunner <>

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.
