[PATCH 5.10 355/663] kselftests: dmabuf-heaps: Fix Makefiles inclusion of the kernels usr/include dir

From: Greg Kroah-Hartman
Date: Tue Mar 02 2021 - 00:06:57 EST


From: John Stultz <john.stultz@xxxxxxxxxx>

[ Upstream commit 64ba3d591c9d2be2a9c09e99b00732afe002ad0d ]

Copied in from somewhere else, the makefile was including
the kerne's usr/include dir, which caused the asm/ioctl.h file
to be used.

Unfortunately, that file has different values for _IOC_SIZEBITS
and _IOC_WRITE than include/uapi/asm-generic/ioctl.h which then
causes the _IOCW macros to give the wrong ioctl numbers,
specifically for DMA_BUF_IOCTL_SYNC.

This patch simply removes the extra include from the Makefile
