Subject: iommu/tegra: remove invalid reference to list iterator variable
X-Git-Tag: v3.6-rc2~26^2~9
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9579a974d1018c7f1d42455c29aa3f0d512c99fe;p=pandora-kernel.git

iommu/tegra: remove invalid reference to list iterator variable

If list_for_each_entry, etc complete a traversal of the
list, the iterator variable ends up pointing to an address
at an offset from the list head, and not a meaningful
structure.  Thus this value should not be used after the end
of the iterator.  Replace c->dev by dev, which is the value
that c->dev has been compared to.

This problem was found using Coccinelle (http://coccinelle.lip6.fr/).
