Subject: [PATCH] iwlwifi: pcie: fix a warning / build failure

drivers/net/wireless/intel/iwlwifi/pcie/drv.c:
        In function ‘iwl_pci_find_dev_info’:
./include/linux/kernel.h:46:25: error: overflow in conversion from
        ‘long unsigned int’ to ‘int’ changes value from
        ‘18446744073709551615’ to ‘-1’ [-Werror=overflow]

Another option would be to #ifdef away iwl_pci_find_dev_info().
