Subject: of/address: Don't loop forever in of_find_matching_node_by_address().
X-Git-Tag: v3.2.72~56
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3ccc6060445dbc7ee6d139102e8fbca362a23a93;p=pandora-kernel.git

of/address: Don't loop forever in of_find_matching_node_by_address().

commit 3a496b00b6f90c41bd21a410871dfc97d4f3c7ab upstream.

If the internal call to of_address_to_resource() fails, we end up
looping forever in of_find_matching_node_by_address().  This can be
caused by a defective device tree, or calling with an incorrect
matches argument.

Fix by calling of_find_matching_node() unconditionally at the end of
the loop.
