That's a bad tool then, as this is used, and the build breaks when this
patch is applied :(

I've dropped it now.

Hm, that's weired, I also checked with:

git grep -n rtw_handle_tkip_mic_err drivers/staging/rtl8188eu/

There were/are no uses and the driver builds and works fine here.
I don't see what I may have missed here. :(

The use of rtw_handle_tkip_mic_err() was added back in commit

69a1d98c831ec64cbfd381f5dcb6697e1445d239
Revert "staging:r8188eu: Use lib80211 to support TKIP"

which was applied with 'Merge 4.18-rc7 into staging-next'.

That was not applied when I sent the patch yesterday,
sorry for the trouble.
