Folks on LKML are pretty good about replying to people with problems, so 
whenever my posts are ignored here I start checking the archives 
(figuring that my problem has probably already been reported and dealt 
with).  :)

Re: Unable to compile 2.5.4: "control reaches end of non-void functionm"

[Steve Kieu]

Hi,

It seems nobody having this problem? No one replies at
least why, so I just want to add one more case of
compiling error. Exactly the same message as yours.

RE: Unable to compile 2.5.4: "control reaches end of non-void functionm"

[J.S.S.]

I have this same problem on both my laptop and my testbox.  It happens
everytime and I have yet to compile 2.5.4 successfully.  Although, I suspect
it's in my config file - I'm just using an old config file I used for my
2.4.17 kernel which works just fine.

If it is in processor.h, search the archives. There was a patch for this
submitted to the list about a week ago.

RE: Unable to compile 2.5.4: "control reaches end of non-void functionm"

[J.S.S.]

Got it. Fixed it.
Still getting the video.o compile problem, but this hasn't been fixed yet
(although it's been discussed a bit, the outcome wasn't too clear).
