+Subject: regmap: debugfs: Fix a reversed if statement in regmap_debugfs_init()
+
+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+commit f6bcb4c7f366905b66ce8ffca7190118244bb642 upstream.
+
+This code will leak "map->debugfs_name" because the if statement is
+reversed so it only frees NULL pointers instead of non-NULL.  In
+fact the if statement is not required and should just be removed
+because kfree() accepts NULL pointers.
+
+Fixes: cffa4b2122f5 ("regmap: debugfs: Fix a memory leak when calling regmap_attach_dev")
