From: Bhumika Goyal Date: Sun, 15 Jan 2017 18:50:28 +0000 (+0530) Subject: drm/etnaviv: constify etnaviv_iommu_ops structures X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bc179f08d26a61f11260ee7528484f317c59e6b0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/etnaviv: constify etnaviv_iommu_ops structures Declare etnaviv_iommu_ops structure as const as it is only used when the reference of one of its field is stored in the ops field of a iommu_domain structure. This ops field is of type const, so etnaviv_iommu_ops structures having similar properties can be declared const too. Done using Coccinelle. Before and after size details of .o file remains the same after cross compiling for arm architecture. lst: Trimmed commit message, apply the same change to iommu_v2.
