[SCSI] ps3rom: fix wrong resid calculation bug
sg driver rounds up the length in struct scatterlist to be a multiple of 512 in some conditions. So LLDs can't use the data length in a sg list to calculate residual. Instead, the length in struct scsi_cmnd should be used. [Geert: the variable buflen already contains scsi_bufflen(cmd)] Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
