[PATCH -next] iommu/exynos: Fix return value check in exynos_iommu_of_setup()

[Andi Shyti]

Hi,

just a question,

is ENOMEM the right return value? of_platform_device_create()
doesn't fail only in case of malloc failure.

Shouldn't it be ENODEV instead, which might also mean with some
imagination that there is no memory available for that device?

Thanks,
Andi
