Subject: [SCSI] sd: Return correct error code for DIF
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=3bf3583b6a49c318f7ed350862d7a217b500e71c;p=linux-edison.git

[SCSI] sd: Return correct error code for DIF

sd_dif.c was not updated to return -EILSEQ, leading to error handling
failures in applications which provide their own integrity metadata (as
opposed to being protected by the block layer functions).
