CVE-2025-71227

A flaw was found in the Linux kernel's mac80211 WiFi subsystem. When a regulatory change disables a channel between the time it is scanned and when a connection attempt is made, a kernel warning (WARN) is triggered. This fix replaces the warning with a more informative error message, as the warning was not appropriate for this recoverable condition.

This is a code quality fix that replaces an inappropriate WARN_ON with an error message. The warning could be triggered by legitimate regulatory domain changes during WiFi operations. No actual crash or security-relevant behavior occurs; the connection simply fails gracefully.
