And entry depends on architecture and on configuration. But don't worry. I use the kernel source to find the MODULES_DEVICE_TABLE (with a partially automated script) to build the new tables. For USB and PNP this works great. For PCI I have some more problems: the item found with MODULES_DEVICE_TABLE are the item marked with '#!'. You see that the not all drivers use MODULES_DEVICE_TABLE.

The sources is always the kernel. giacomo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
