Subject: xen/blkback: use drv_get/set_drvdata rather than directly accessing driver_data.
X-Git-Tag: upstream/snapshot3+hdmi~10171^2~16^2~61
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5cf6e4f6f6d5549904db6ecb3ffd5b8f71f41250;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

xen/blkback: use drv_get/set_drvdata rather than directly accessing driver_data.

Direct driver_data access is obsolete and will disappear.
