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
