| |
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.
Signed-off-by: Arnd Bergmann <arnd@arndb.de> --- This is an old warning I see rarely on ARM randconfig builds.
