Subject: SCSI: remove fake "address-of" expression
X-Git-Tag: upstream/snapshot3+hdmi~13752
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e6da54d84f9286edbe4c92ff5023ff481ce2a5c9;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

SCSI: remove fake "address-of" expression

Fake "address-of" expressions that evaluate to NULL generally confuse
readers and can provoke compiler warnings.  This patch (as1411) removes
one such fake expression, using an "#ifdef" in its place.
