SubjectRE: [PATCH 2/2] mtd: cmdlinepart: use cmdline partition parser lib

The next '-' partition be ignore at function "cmdline_parts_set", and the client will get a right result.
Is there any other worry about '-' I don't know ?

I understand your worry about, we use cmdlinepart many years.
I will spend time to make block/cmdline-parser.c fully equivalent to the
parser in drivers/mtd/cmdlinepart.c.
