[PATCH] Fix kdev_t in st.c (2.5.2-pre7)

[PATCH] Fix kdev_t in st.c (2.5.2-pre7)

[Jonathan Corbet]

Since yesterday's patch, sr and sg appear to have been fixed, but the SCSI
tape driver still has kdev_t problems.  Having fat-fingered my way into a
disk disaster yesterday, I have a real interest in a working tape drive :)
Here's a rework of my st.c kdev_t patch for 2.5.2-pre7.
