Subject: [PATCH 24/26] USB: core: constify vm_operations_struct
References: FATE#321327
Patch-mainline: v4.14-rc1
Git-commit: b64d47ae62e5f56727ad6dc2088e13dfab524a83

vm_operations_struct are not supposed to change at runtime.
All functions working with const vm_operations_struct.
So mark the non-const structs as const.
