  Hi Hans,

Thanks for this.

There are indeed duplicates.  I removed the older one and dmesg went 
wild :)  Dump follows at end of email.

However looking at the tree structure I have to say I don't understand 
it.  Firstly there seem to be two equivalent branches in /lib/modules/:

1) drivers/linux/drivers/misc/altera-stapl/

and

2) drivers/misc/altera-stapl/

Before I do the patch and build, altera-stapl.ko is in 2) but the make 
install puts the new version in 1).

If I delete the version in 1), I delete the effects of the patch, if I 
delete the version in 2), I get the dump below.

I upgraded to 3.11.0.19 and reinstalled linux tv, but same effect.

Note that the dump here gives err 0, but the original error was err 
-22.  Is -22 significant, does anyone know what it means?

Also, there is an altera.h of size = 0 in 
lib/modules/...../include/config/spi but as it is not duplicated on 
linuxtv/media_build I imagine it doesn't affect the compile.

There has been quite a bit of discussion about this error in previous 
releases and patches have been applied (as I'm sure you saw).  It seems 
we still haven't quite got to the bottom of it as it is still 
reappearing.  I think it would be quite useful to put it to bed once and 
for all.

Thanks so much for your help.

Regards

Steve.
