They're aliases. On the x86 my e1000 Ethernet driver loads using this alias name: "pci:v00008086d00001010sv*sd*bc*sc*i*" In fact, the e1000 driver has 63 alias names in addition to "e1000" But it's still the e1000 driver after it is loaded. [EMAIL PROTECTED]:/home/linux/drivers/net/e1000$ lsmod | grep e1000 e1000 115968 0 Loading a I2C driver with an OF alias name is not going to change the module name after it is loaded. In fact, once the module is in memory there's no way to tell what name was used to load it. OF device names are set by the Open Firmware committee. It is not reasonable to force the Linux names back into Open Firmware since this would force the other operating systems using Open Firmware to adopt the Linux names. This issue hasn't been visible before since there was a global table in the PowerPC code mapping all known Open Firmware names into linux names. Keeping this as a global table doesn't scale. The mapping needs to be done by each device individually. > > -- > Jean Delvare > -- Jon Smirl [EMAIL PROTECTED] -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
