那类似这个路径里面算不算有驱动？

$ ll /sys/devices/platform/serial8250/driver/
total 0
drwxr-xr-x  2 root root    0 Oct 25 18:07 ./
drwxr-xr-x 55 root root    0 Oct 25 18:07 ../
--w-------  1 root root 4096 Oct 26 00:07 bind
lrwxrwxrwx  1 root root    0 Oct 26 00:07 serial8250 -> ../../../../devices/platform/serial8250/
--w-------  1 root root 4096 Oct 25 18:07 uevent
--w-------  1 root root 4096 Oct 26 00:07 unbind
