Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> memory: pl353-smc: Fix refcount leak bug in pl353_smc_probe()<br /> <br /> The break of for_each_available_child_of_node() needs a<br /> corresponding of_node_put() when the reference &amp;#39;child&amp;#39; is not<br /> used anymore. Here we do not need to call of_node_put() in<br /> fail path as &amp;#39;!match&amp;#39; means no break.<br /> <br /> While the of_platform_device_create() will created a new<br /> reference by &amp;#39;child&amp;#39; but it has considered the refcounting.
