Ok, then maybe it's not 3.14.5

It's a little bit unclean since the kernel is from this repo :

git://git.yoctoproject.org/linux-yocto-3.14.git commit 
144595ef6215a0febfb8ee7d0c9e4eb2eaf93d61

Fact is that master supports the MC73xx, and I seem to be running a kernel 
that does not.

Does it make any difference whether I chose patching sierra.c og qcserial.c ?
