Hi Larry,

Both patches look good to me, however I've already submitted a patch 10
days ago that does exactly what your rtw_xmit.c patch does, in
addition to fixing the changed error handling semantics for the relevant
function (in f94b47c6bde6) which broke the driver.

Regards,
Phil

Phil,

Sorry I missed your patch. I have been really busy the past month on another 
problem, and I was not paying much attention to r8188eu.

When I built a mainline kernel in the middle of the merge from 5.18 to 5.19, 
those two warnings stood out.

Your patch should be ahead of mine in Greg's queue, thus mine should fail, and I 
will get the "does not apply" message. At that time, I will send the other 
patch. As both of us missed the 5.19 merge, the build warnings will persist 
until 5.20, but no harm.

Larry

I've taken Phillip's patch, and your second patch here, both for
5.19-final, so all should be good now.

thanks,

Please don't be sorry - just wanted you to know in advance :-).

Figured if I said nothing I would probably aggravate the situation. I
don't have much time to spend on r8188eu myself either so don't worry.

All the best,
Phil
