4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
commit 3021376d6d12dd1be8a0a13c16dae8badb7766fd upstream.
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.
