The array fields in struct wmi_start_scan_arg that are checked here are fixed size arrays so they can never be NULL. Maybe that helps rephrasing this commit message. Definitely.

[PATCH] net: wireless: ath: ath10k: remove unnecessary code
The name of an array used by itself will always return the array's address. So these tests will always evaluate as false and therefore the _return_ will never be executed. Signed-off-by: Gustavo A.
