Subject: drm/radeon/kms: Fix NULL pointer dereference if memory allocation failed.
X-Git-Tag: v2.6.34-rc4~88^2~23
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fcbc451ba1948fba967198bd150ecbd10bbb7075;p=pandora-kernel.git

drm/radeon/kms: Fix NULL pointer dereference if memory allocation failed.

When there is allocation failure in radeon_cs_parser_relocs parser->nrelocs
is not cleaned. This causes NULL pointer defeference in radeon_cs_parser_fini
when clean up code is trying to loop over the relocation array and free the
objects.

Fix adds a check for a possible NULL pointer in clean up code.
