Subject: mtd: cmdlinepart: skip partitions truncated to zero
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ebf4f0707df410a7666ec409ee68dc068db56e97;p=deliverable%2Flinux.git

mtd: cmdlinepart: skip partitions truncated to zero

Perform flash size truncation before skipping zero sized partition
so that if the result is a zero sized, it will be skipped like the
others.
