[PATCH] cxgbit: fix dma_addr_t printk format

From: Arnd Bergmann
Date: Fri Mar 04 2016 - 19:05:13 EST


The newly added driver prints a dma_addr_t using the %llx format string,
but that is wrong on most 32-bit architectures:

drivers/target/iscsi/cxgbit/cxgbit_ddp.c: In function 'cxgbit_dump_sgl':
drivers/target/iscsi/cxgbit/cxgbit_ddp.c:180:10: error: format '%llx' expects argument of type 'long long unsigned int', but argument 8 has type 'dma_addr_t {aka unsigned int}' [-Werror=format=]
pr_info("\t%d/%u, 0x%p: len %u, off %u, pg 0x%p, dma 0x%llx, %u\n",

Unfortunately, we can't use the %pad format string here because
we are not printing an lvalue, so we have to add a cast to u64, which
matches the format string on all architectures.
