Subject: iommu/dmar: Remove redundant assignment of ret
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3f6db6591a2decad5f223a7dcfc01d2a3c15e187;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

iommu/dmar: Remove redundant assignment of ret

There is no need to assign ret to 0 in some cases. Moreover it might
shadow some errors in the future.

Remove such assignments.
