[PATCH 4.17 086/336] selftests/filesystems: devpts_pts included wrong header

[Greg Kroah-Hartman]

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Anders Roxell <anders.roxell@xxxxxxxxxx>

[ Upstream commit dd4b16b4f9b1b7d9f4a185cb8222e42f3a5daf00 ]

We were picking up the wrong header should use asm/ioctls.h form the kernel
and not the header from the system (sys/ioctl.h). In the current code we
added the correct include and we added the kernel headers path to the CFLAGS.
