The conflict resolution looks accurate to a non-expert eye.

I can also confirm there are no new findings reported by:
 - make W=1
 - make C=2
 - cppcheck --enable=all --force --inconclusive
 - PVS-Studio

PS: Could you help me out how (and if at all possible) to preserve the
Author date of the original patch when downloading and applying the
'raw' file provided by lore.kernel.org ?

Thanks,
Eugeniu
