You said that clocks are NOT stopped when applying patch 2/4 without 1/4.
I detailed a fairly likely code path.

When I said I 'resent' it, my meaning was not to let you understand that I did not modify it obviously.

I could say the same about the current status and handling but I will ask you to point precise points instead, please.
As of the current status of the driver there is not even full duplex, maintainance is likewise.
The patches I am sending are quite easy to discuss.

Could you point what is wrong in the code or comments ?
Nitpicking about "A repost is where you send exactly the same thing again." and talking so much about
pb applying 2/4 without 1/4 really sucks.

I said and am saying my patches improve greatly the code quality/functionnality, if you think otherwise, give tangible reasons and I'll be really happy to discuss/rework/abandon the patches.

Since I have no feedback from Maintainers, I am pinging the original author hoping I won't disturb too much.
