[yocto] Fwd: preempt-rt for 4.14.71 fails to build

[Dimitris Tassopoulos]

Hi all!

I've tried to build the latest preempt-rt kernel from the
`v4.14/standard/preempt-rt/base`
and it fails to build. These are the hashes I've used:

```
LINUX_VERSION = "4.14.71"
SRCREV_machine = "c37a14708f5b618602f84f83f902346e055824c3"
SRCREV_meta = "1fb0b0379fb5883ce5af7485374e3f78ee4272d3"
```

And the errors I get are:
```
/rnd/yocto/nativeos/build/tmp/work-shared/congatec/kernel-source/kernel/locking/rtmutex.c:

/rnd/yocto/nativeos/build/tmp/work-shared/congatec/kernel-source/kernel/locking/rtmutex.c:2044:48:

```

Is there any change that the latest rt44 patches are nor applied?

Thanks!
Dimitris
