Subject2.1.0 patches, aha1542, ncpfs, sound, umsdos

drivers/scsi/aha1542.c - Correct out by one error (thanks to John Shifflett
<jshiffle@netcom.com>). Cosmetic change SCSI_PA to
SCSI_BUS to better match the memory model.
fs/ncpfs/dir.c, file.c - Correct definition of read/write routines to match
new file_operations.
Various sound modules - Correct definition of read/write/seek routines to
match new file_operations. Remove complaint about
unused routine.
fs/umsdos/emd.c - Correct definition of read/write routines to match
new file_operations.

Subject: Patch: linux-2.1.0/drivers/block/rd.c
Hi,

I had to apply the following patch in order to compile the "official"
2.1.0 kernel when using the ramdisk. The comments also contained
references to lseek, but I didn't change them as they don't appear to
have changed elsewhere :-)

Regards,
Julian
