[v3,02/13] software node: Simplify software_node_release() function

Commit Message

Heikki Krogerus April 12, 2019, 1:41 p.m. UTC

It's possible to release the node ID immediately when
fwnode_remove_software_node() is called, no need to wait for
software_node_release() with that. This change has no
functional effect.
