    dmaengine: bcm2835: fix 64-bit warning · 4aa819c7

    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.
