Sorry, I am not clear this rule before. But I found the same issue independently. It looks good 
after changging the erase size for phram driver. Then when I try to send the patch, I found that 
Patrick O'Grady has already send a patch which has not been merged as the link below
https://lore.kernel.org/lkml/CAJ7m5OqYv_=JB9NhHsqBsa8YU0DFRoP7C+W10PY22wonAGJK=A@mail.gmail.com/

So I resend a patch with some change and fix for mainline kernel with the old patch link of Patrick O'Grady.

If I need to change the authorship, I will resend this patch for V3 with authorship of Patrick O'Grady.
