解决 Linux系统上驱动交叉编译时出现：asm/types.h: No such file or directory

解决 Linux系统上驱动交叉编译时出现：

include/uapi/linux/types.h:5:10: fatal error: asm/types.h: No such file or directory

内核版本：5.4.47

解决方案：对比内核版本4.1.35版本发现，在内核顶层的Makefile的LINUXINCLUDE宏中少加入了-I$(objtree)/arch/$(SRCARCH)/include/generated/uapi路径，加入后编译正常。

# Use LINUXINCLUDE when you must reference the include/ directory.
# Needed to be compatible with the O= option
LINUXINCLUDE    := \
        -I$(srctree)/arch/$(SRCARCH)/include \
        -I$(objtree)/arch/$(SRCARCH)/include/generated/uapi \
        -I$(objtree)/arch/$(SRCARCH)/include/generated \
        $(if $(building_out_of_srctree),-I$(srctree)/include) \
        -I$(objtree)/include \
        $(USERINCLUDE)
