Hi Jiri,

You mentioned in the discussion and I quote: "*If* wireless maintainers 
think otherwise, I'll send a revert request to Linus for 
consideration.". However, you did not wait for any response from the 
wireless maintainers nor from the author of the patch you are reverting. 
Seems like an overreaction to me though personally I do not disgree with 
the revert itself.

Regards,
Arend
