Although such a warning is desirable, the current implementation overflows the dmesg buffer with thousands of warnings, all of which are the same. A WARN_ONCE() call is sufficient. Fixes: dc09766c755c {"wifi: wireless: warn on most wireless extension usage") Signed-off-by: Larry Finger --- Kalle, If accepted, this patch should be send to kernel 6.3.
