When building this driver on arm64, we get a harmless type mismatch warning: drivers/dma/bcm2835-dma.c: In function 'bcm2835_dma_fill_cb_chain_with_sg': include/linux/kernel.h:743:17: warning: comparison of distinct pointer types lacks a cast (void) (&_min1 == &_min2); \ ^ drivers/dma/bcm2835-dma.c:409:21: note: in expansion of macro 'min' cb->cb->length = min(len, max_len); This changes the type of the 'len' variable to size_t, which avoids the problem.
