I know the history of this, lately (last year) it was again a discussion result
of which is linux/unaligned.h. But this recommendation is only for the leaf files
or custom (local) headers and code, it doesn't fully applicable to the globally
accessed headers, like gpio/consumer.h. I consider this as false positive by
checkpatch.

Yes, I will check more on the header nevertheless.
