That was meant to be "Ref:" and was meant to show commit that introduced concept of dynamic partitions. I thought it's a new feature not everyone may be familiar with yet. I thought it may help to review this patch. If that is pointless though could you Rob just drop those tags while applying, please? I guess I'll just let you decide. >> Ref: dd638202dfb65 ("dt-bindings: mtd: partitions: add additional example for qcom,smem-part") >> Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

Ah nw, I wasn't sure if it ws a typo or "Reg" short for regression. > > If that is pointless though could you Rob just drop those tags while > applying, please?
