Subject[PATCH v2 2/2] staging: ion: chunk_heap: use %pad for printing dma_addr_t's
We're currently using %lu and %ld to print some variables of type
dma_addr_t, which results in the following warning when dma_addr_t is
64-bits wide:

drivers/staging/android/ion/ion_chunk_heap.c: In function 'ion_chunk_heap_create':
drivers/staging/android/ion/ion_chunk_heap.c:176:2: warning: format '%lu' expects argument of type 'long unsigned int', but argument 3 has type 'dma_addr_t' [-Wformat=]
pr_info("%s: base %lu size %zu align %ld\n", __func__, chunk_heap->base,
drivers/staging/android/ion/ion_chunk_heap.c:176:2: warning: format '%ld' expects argument of type 'long int', but argument 5 has type 'dma_addr_t' [-Wformat=]

Fix this by using %pad as instructed in printk-formats.txt.
