OK, the nasty games continue and the message is not getting through.

An appropriate response by a maintainer would have been to request I
revise the code according to the way it has currently and elegantly
revised in.

[PATCH v2] rtl8xxxu: Fix for agressive power saving by rtl8723bu wireless IC

where I use a simple pointer comparison of priv->fops with &rtl8723bu_fops.

As far as I can see there is nothing more to be done on my part code
wise. The supposed issue with matching functions, as far as I can see,
is a non issue.

If you want to comment on comments in patch messages please do so on
the above current proposed patch instead of dragging up stale and
irreelvant patch proposals to make a petty point.

Jes has now moved the goal posts, indicating all drivers for rtl8xxxu
need to be tested fro similar issues. If there are problems with other
rtl8xxxu drives then it is not my problem and has nothing to do with
me. My issue is only with the rtl8723bu driver.

Such doubts also makes it look as if there was never any proper
testing and there is no real interest in proper testing. After all
that would involve cooperation and team work.

Want concrete evidence? I actually did report problems to Jes in
private emails, AS REQUESTED, in dmesg before I started tests and
posting patches. In the emalI stated I was willing to test drivers
with printk messages. I did not even get the courtesy of a reply.

Want even more concrete evidence? Jes has some very strange comments
in his tree for his current last commit
f958b1e0806c045830d78c4287fbcddf9e5fd9d0

" This uncovered a huge bug where the old code would use struct
ieee80211_rate.flags to test for rate parameters, which is always
zero, instead of the flags value from struct ieee80211_tx_rate.

"Time to find a brown paper bag :("
