parport_serial and serial driver?
Hi,
I use non-modular kernel with parport_serial driver built in (NetMos-based cards, 2.4.latest-vanilla patched for NetMos PCI IDs). The problem is that parport_serial is initialized before serial driver and thus both serial ports on that card are detected as ttyS00. This patch helped me:

When the same kernel has parport_serial as a module, everything works fine, because serial is already initialized.
BTW - Is there a way to specify the order of initialization (module_init) of certain drivers? What is the proper solution to my problem?

Doesn't that then break ppdev? I think the correct solution was posted here not long ago---to add a call to the serial driver's init function in parport_serial (with a protection against it being run multiple times).
