I found ath12k-check output many logs, about 5000 lines.

And ath12k-check only has one item in CHECKPATCH_IGNORE, it does not 
have the other items which

existed in ath10k-check/ath11k-check, so ath12k-check output many info

"struct  should normally be const"/"networking block comments don't use 
an empty /* line, use /* Comment..."/.

Also it print many "note: in included file ..." by sparse.


May I change ath12k-check with diff below and use "ath12k-check | grep 
-v "note: in included file"" for the patch check?
