Subject: software node: Initialize the return value in software_node_find_by_name()
X-Git-Tag: v5.4-rc1~140^2

software node: Initialize the return value in software_node_find_by_name()

The software node is searched from a list that may be empty
when the function is called. This makes sure that the
function returns NULL if the list is empty.

Fixes: 1666faedb567 ("software node: Add software_node_find_by_name()")
