> Subject: [PATCH] infiniband: cxgb4: use %pR format string for printing resources
> 
> The cxgb4 prints an MMIO resource using the "0x%x" and "%p" format
> strings on the length and start, respective, but that
> triggers a compiler warning when using a 64-bit resource_size_t
> on a 32-bit architecture:
> 
> drivers/infiniband/hw/cxgb4/device.c: In function 'c4iw_rdev_open':
> drivers/infiniband/hw/cxgb4/device.c:807:7: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
>        (void *)pci_resource_start(rdev->lldi.pdev, 2),
> 
> This changes the format string to use %pR instead, which pretty-prints
> the resource, avoids the warning and is shorter.

> This is an old warning I see rarely on ARM randconfig builds.
