Subject: mtd: plat_ram: call mtd_device_register only if partition data exists
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c32987918efaa6949c5b2f3e43b654a742b18f7d;p=linux-beck.git

mtd: plat_ram: call mtd_device_register only if partition data exists

mtd_device_parse_register() registers the device as a whole if no
partition data is passed so there is no reason to call
mtd_device_register() after that.
