Remove the last 'else' checking to fix this error.
Missing fixes tag.
From my understanding, fixes tags are for patches that fix bugs (hw is not
working etc) and not a warning message from dtbs_check. So my point of view
would be to not add a fixes tag here.
Not conforming to bindings is also a bug. Missing properties or wrong
properties, even if hardware is working, is still a bug. If such bug is
not visible now in Linux, might be visible later in the future or
visible in different OS (DTS are used by other systems and pieces of
software like bootloaders). Limiting this only to Linux and to current
version (hardware still works) is OK for Linux drivers, but not for DTS.
If a wrong DTS breaks software, then it's worth a fixes tag, especially for the
DTS part, we could argue about the bindings part, but in that case it would be
Therefore Fixes tag in general is applicable. Of course maybe to this
one not really, maybe this is too trivial, or whatever, so I do not
insist. But I insist on the principle - reasonable dtbs_check warnings
are like compiler warnings - bugs which have to be fixed.
I'm not arguing that these things shouldn't be fixed, but that they are worth
being back-ported to the stable branches.
