YueHaibing · rafaeljw · commit 0e3edd944480 · 2019-03-19T16:37:56.000+01:00
Fix sparse warning:

drivers/base/swnode.c:475:22: warning: symbol 'software_node_get_parent' was not declared. Should it be static?
drivers/base/swnode.c:484:22: warning: symbol 'software_node_get_next_child' was not declared. Should it be static?
