dma-debug: Fix compile warning with PAE enabled (59a40e70) · Commits · 戴 / test

When PAE is enabled in the kernel configuration the size of phys_addr_t differs from the size of a void pointer. The gcc prints a warning about that in dma-debug code. This patch fixes the warning by converting the output to unsigned long long instead of a pointer. Signed-off-by:
