让驱动自动加载

/etc/moudles 加入模块名，不要加.ko

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

depmod
depmod - program to generate modules.dep and map files
当把模块文件放到/lib/module/`uname -r`/目录下，运行depmod，则会在/lib/modules/<kernel-version>/目录下生成modules.dep(.bb)文件，表明了模块的依赖关系
