Here are the remaining kdev_t fixes for
linux-2.5.2-pre7/drivers/cdrom. Note that sbpcd.c still will not compile,
due to it apparently needing some bio changes that I haven't looked
into yet. However, my changes are quite mechanical, so the spbcd.c
changes are a step toward making it compile. The changes make the
other drivers compile (sonycd535.c and sjcd.c).
I only know that these change eliminate compilation error.
There are otherwise completely untested.
