[PATCH v4] x86/kaslr: Remove redundant if check in slots_fetch_random()

Thorsten Blum <[email protected]>
Newsgroups gmane.linux.kernel
Message-ID <[email protected]>
The loop in slots_fetch_random() either returns the slot address or
exits with i == slot_area_index, making the if check redundant. Drop it.
