Subject: [PATCH] libata: fix ata_xfer_tbl termination
X-Git-Tag: v2.6.17-rc1~28^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=be9a50c8524b53003e5fa32f072945772ffd13a5;p=platform%2Fkernel%2Flinux-exynos.git

[PATCH] libata: fix ata_xfer_tbl termination

ata_xfer_tbl is terminated by entry with -1 as ->shift.  However,
->shift was unsigned int making the termination condition bogus.  This
patch converts ->shift and ->bits to int.
