I'm sorry I mean this patch "staging: greybus: add blank line after
struct", Julia I understood the issue

but I am confused about how to fix it, should I drop the patch that
added the newline? then what should I do?

and version that I have submitted, should I do anything about it as you
said it is wrong solution?
