Hello,
just some warnings I encountered when compiling this today:
drivers/iommu/exynos-iommu.c: In function ‘exynos_iommu_of_setup’:
drivers/iommu/exynos-iommu.c:1177:2: warning: passing argument 2 of
‘of_iommu_set_ops’ discards ‘const’ qualifier from pointer target type
[enabled by default]
of_iommu_set_ops(np, &exynos_iommu_ops);
^
In file included from drivers/iommu/exynos-iommu.c:23:0:
include/linux/of_iommu.h:34:6: note: expected ‘struct iommu_ops *’ but
argument is of type ‘const struct iommu_ops *’
void of_iommu_set_ops(struct device_node *np, struct iommu_ops *ops);
^
I guess the 'const' should be dropped from exynos_iommu_ops, even though
I wonder why of_iommu_set_ops wants a non-const pointer (can/does it
modify the struct later on?).
With best wishes,
Tobias
