From b9504247a6eb2bd68e3f620ca1f3fbe7309123ea Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Sun, 25 Jun 2017 20:22:57 +0200 Subject: mtd: Fix check in mtd_unpoint() The code checks that ->_point is not NULL, but we should actually check ->_unpoint value which is dereferenced a few lines after the check.
