When you answer a mail, it is customary to strip the signature. Most
civilized mail user agent do this for you. In fact, it is even
customary to only keep the part of the mails which are relevant for
your answer (but very few people do that nowadays).

No, the file
https://xenomai.org//downloads/ipipe/v3.x/arm/older/ipipe-core-3.14.44-arm-16.patch
does not contain this hunk. So, if the patch you are using contains
this hunk, you are not using ipipe-core-3.14.44-arm-16.patch.

Anyway, I can find the hunk a patch contains, downloading the patch
from the server. This is not what I am asking you. The question I
have been trying to ask three times and to which I can not find the
answer because I do not have the sources you use is: does the device
tree file you use include imx6ql.dtsi?

When you do not understand a question, I prefer you to tell me,
rather than giving a random answer. This is very irritating.
