That's not good, why not just submit a patch to add the needed support, and then all versions of the kernel will work with your device and you will not have to do any extra work at all? > Then I found that 8250_pci.c can support our card except that following > information in file. > /*Unknow vendors/cards - this should not be in linux/pci_ids.h*/ > #define PCI_SUBDEVICE_ID_UNKNOWN_0x1584 0x1584 =====> Yes, this is RAYON's > P584 card. > #define PCI_SUBDEVICE_ID_UNKNOWN_0x1588 0x1588 =====>Yes, this is RAYON's > P588 card. > > I don't know who and when offer such support.

Can you make up a patch for the code and send it to us (read Documentation/SubmittingPatches for how to do this) and we can apply it to the tree? That way I understand exactly what changes you need for your devices. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
