2022-06-21mips: lantiq: falcon: Fix refcount leak bug in sysctrlLiang He1-0/+6
In ltq_soc_init(), of_find_compatible_node() will return a node pointer with refcount incremented. We should use of_node_put() when it is not used anymore. Signed-off-by: Liang He <windhl@126.com> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2022-03-30MIPS: lantiq: check the return value of kzalloc()Xiaoke Wang1-0/+2
kzalloc() is a memory allocation function which can return NULL when some internal memory errors happen. So it is better to check the return value of it to prevent potential wrong memory access or memory leak.
