[Patch] Signdness issue in drivers/scsi/osst.c

[Eric Sesterhenn <snakebyte@gmx.de>]

Hi,

another signdness warning from gcc 4.1

drivers/scsi/osst.c:5154: warning: comparison of unsigned expression < 0 is always false

The problem is that blk is defined as unsigned, but all usages of it
are normal int cases. osst_get_frame_position() and osst_get_sector()
return ints and can return negative values. If blk stays an unsigned int,
the error check is useless.
