You don't need 'else' after a 'return'.
I'd also put the return nearer the test.
While the above could be written:
return dmi_check_system(bt_fwbug_list) &&
(pci_get_device(PCI_VENDOR_ID_INTEL, 0x24F3, NULL) ||
pci_get_device(PCI_VENDOR_ID_INTEL, 0x24FD, NULL) ||
pci_get_device(PCI_VENDOR_ID_INTEL, 0x2526, NULL));
I think I'd write:
if (!dmi_check_system(bt_fwbug_list))
return 0;
return pci_get_device(PCI_VENDOR_ID_INTEL, 0x24F3, NULL) ||
pci_get_device(PCI_VENDOR_ID_INTEL, 0x24FD, NULL) ||
pci_get_device(PCI_VENDOR_ID_INTEL, 0x2526, NULL);
