[PATCH 04/11] mtd: ofpart: do not fail probe when no partitions exist

[Michal Suchanek]

On Exynos it is necessary to set SPI controller parameters that apply to
a SPI slave in a DT subnode of the slave device. The ofpart code returns
an error when there are subnodes of the SPI flash but no partitions are
found. Change this condition to a warning so that flash without
partitions can be accessed on Exynos.
