In doing so,\nit unintentionally removed an offset alignment check done through calls\nto binder_alloc_copy_from_buffer() -> check_buffer().\n\nThese calls were replaced in binder_get_object() with copy_from_user(),\nso now an explicit offset alignment check is needed here. This avoids\nlater complications when unwinding the objects gets harder.\n\nIt is worth noting this check existed prior to commit 7a67a39320df\n(\"binder: add function to copy binder object from buffer\"), likely\nremoved due to redundancy at the time."
