[lvc-project] [PATCH 2/2] wifi: ath11k: annotate ch_param of struct scan_chan_list_params with __counted_by

[Dmitry Antipov]

According to 'ath11k_reg_update_chan_list()', annotate flexible
array member 'ch_param' of 'struct scan_chan_list_params' with
'__counted_by()' attribute to improve runtime bounds checking
when CONFIG_UBSAN_BOUNDS is enabled. Compile tested only.
