CVS commit: src/sys/dev/scsipi

[Reinoud Zandijk <reinoud%netbsd.org@localhost>]

Module Name:    src
Committed By:   reinoud

        src/sys/dev/scsipi: cd.c

Log Message:
The size of struct scsipi_read_discinfo_data is not even due to the data[1]
pseudo array in the structure. The scsi command issued used
sizeof(scsipi_read_discinfo_data) but included thus the last byte that
wasn't going to be inspected anyway. Using the constant
READ_DISCINFO_BIGSIZE fixes the bug.

Even though SCSI adapters *should* accept odd lengths, the Sun U10
(sparc64's) crashes in bus_space_read_multi_stream_2(). That explains the
crash.

NOTE: somewhere in NetBSD/sparc64's atapibus support there is the
assumption on the even size; this needs to be fixed! (Hi Sparc64 portmaster
:-) )
