[yocto] Set Default Kernel Version Q

[Albert K]

Hi,

I have set the PREFERRED_VERSION_linux-yocto = "3.17%"  in the

~/porky/build/conf/local.conf but it does not seem to be working.
Where can I set so that the default kernel version is used (currently
is compiling with kernel 3.14 with dizzy).   Thanks.

Regards,
Albert
