From b4e7a7a88b5d060650094b8d3454bc521d669f6a Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 8 Jun 2018 11:17:54 -0400 Subject: drm_mode_create_lease_ioctl(): fix open-coded filp_clone_open() Failure of ->open() should *not* be followed by fput(). Fixed by using filp_clone_open(), which gets the cleanups right.

To fix this just do not expose the type at all - this somewhat mirrors pselect() where we do not even have a type for the magic sigmask argument, but just use pointer arithmetics.
