Subject: [PATCH v2 0/2] wifi: ath11k: fix event locking

RCU lockdep reported suspicious RCU usage when accessing the temperature
sensor. Inspection revealed that the DFS radar event code was also
missing the required RCU read-side critical section marking.

Changes in v2
 - add the missing rcu_read_unlock() to an
   ath11k_wmi_pdev_temperature_event() error path as noticed by Jeff
