Subject: iommu/dmar: Remove redundant ' != 0' when check return code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f9808079aa7626d71215a71661dbed5c4ff101d2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

iommu/dmar: Remove redundant ' != 0' when check return code

Usual pattern when we check for return code, which might be negative
errno, is either (ret) or (!ret).

Remove extra ' != 0' from condition.
