Description
If there's no OCB state, don't ask the driver/mac80211 to leave, since that's just confusing. Since set/clear the chandef state, that's a simple check.

Remediation
Red Hat statement
This is a minor logic fix in the WiFi cfg80211 subsystem for OCB mode, which is used in vehicular networking (802.11p/DSRC). The issue does not cause a crash but could lead to confusing driver behavior. Most systems do not use OCB mode, significantly limiting the impact.
