Does this patch applies only to 5.9.1 ? If so, it should go in
package/qt5/qt5declarative/5.9.1/.

I can fixup the patch, just tell me if this issue is only applicable to
5.9.1 (I guess it is the case, but I prefer to ask).

Thanks,

Thomas

[Petar Koretic]

Hi Thomas.

Thanks for the information.
It does affect and applies to Qt 5.8 (and 5.9.0) as well, just tested this
to confirm it.
Commit message needs fixing then, sorry.

Best regards,
Petar

[Buildroot] [PATCH 1/1] qt5declarative: backport 'Fix alignment issue on ARMv7' patch to 5.9.1

Doesn't affect or apply to 5.6, if that was actually the question.

Best regards,
Petar

You should add your Signed-off-by here, and a link to the upstream bug
report or commit (I see you wrote the task number and change-id, but a
direct link is preferable).

Since anyway the patch was not entirely correct because it should be in
the 5.9.1/ subfolder, can you resend an updated version that takes into
account those small comments?

Thanks a lot!

[Buildroot] [PATCH 1/1] qt5declarative: backport 'Fix alignment issue on ARMv7' patch to 5.9.1

[Petar Koretic]

Hi Thomas.

I've added Signed-off-by and a link to the upstream bug to my buildroot
patch that adds the patch from the Qt commit that is linked.
You want me to add Signed-off-by and qt bug report link to the Qt patch?
Because in the end I just took the patch from the Qt commit in 5.9 upstream
branch so I have no affiliation to that.

Thanks,
Petar

Yes, please.

Signed-off-by means that you are in the chain of people from the
original author of the patch to where the patch was being added, so it
makes sense to add your Signed-off-by in the Qt patch as well, since
you're pushing it to the Buildroot project.

Thanks!
