Smatch throws below error drivers/net/wireless/ath/ath12k/mac.c:8318 ath12k_mac_op_get_survey() error: we previously assumed 'sband' could be null Currently, we access sband inside the null check of the sband in ath12k_mac_op_get_survey(). Fix this issue by removing the entire if block, because decrement idx is unnecessary since there are no more band to test.
