[PATCH] leds: netxbig: fix an OF node reference leak in netxbig_leds_get_of_pdata()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



netxbig_leds_get_of_pdata() does not release the OF node obtained by
of_parse_phandle() when of_find_device_by_node() fails. Add an
of_node_put() call to fix the leak.

This bug was found by an experimental static analysis tool that I am
developing.
