[Greg Kroah-Hartman]

4.12-stable review patch.  If anyone has any objections, please let me know.

[ Upstream commit d94708a553022bf012fa95af10532a134eeb5a52 ]

Commit de77ecd4ef02 ("bonding: improve link-status update in mii-monitoring")
moves link status commitment into bond_mii_monitor(), but it still relies
on the return value of bond_miimon_inspect() as the hint. We need to return
non-zero as long as we propose a link status change.
