Run your patches thru >scripts/checkpatch.pl before posting, please. Those spaces were actually left out purposely: The file in question (typhoon.c) is missing those spaces between the statements (if, for, while) and the following opening bracket pretty much always (except 2-3 times) and we figured that it might be better to keep the coding style consistent since this might aswell have been intended by the original author. > >> err_msg = "Could not get Sleep Image version"; >> goto error_out_reset; >> } >> @@ -2453,7 +2455,8 @@ typhoon_init_one(struct pci_dev *pdev, const struct pci_device_id *ent) >> dev->features = dev->hw_features | >> NETIF_F_HW_VLAN_CTAG_RX | NETIF_F_RXCSUM; >> >> - if(register_netdev(dev) < 0) { >> + err = register_netdev(dev); >> + if(err < 0) { > > Same here. > >[...] > >MBR, Sergei But of course we can provide you with a patchset including those spaces.
