Subject: ata: sata_dwc_460ex: remove variable num_processed
X-Git-Tag: v6.6.17~5961^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=de58fd3d80f884f7f322a06bfe08465e49b47c5d;p=platform%2Fkernel%2Flinux-rpi.git

ata: sata_dwc_460ex: remove variable num_processed

Variable num_processed is just being incremented and it's never used
anywhere else. The variable and the increment are redundant so
remove it.
