Subject: mmu_notifiers: fixup comment in mmu_interval_read_begin()
Date: Tue, 25 Jul 2023 23:42:04 +1000
The comment in mmu_interval_read_begin() refers to a function that doesn't
exist and uses the wrong call-back name. The op for mmu interval
notifiers is mmu_interval_notifier_ops->invalidate() so fix the comment up
to reflect that.
