When exposing data access through debugfs, the correct debugfs_create_*() functions must be used, depending on data type.
Remove all casts from data pointers passed to debugfs_create_*() functions, as such casts prevent the compiler from flagging bugs. omap_iommu.nr_tlb_entries is "int", hence casting to "u8 *" exposes only a part of it. Fix this by using debugfs_create_u32() instead.
