How can I find out what is the driver for device node '/dev/video11'

Question

In linux kernel, a device (e.g. camera) can register as a file (e.g. /dev/video11). How can I find out from the code which driver is registered as /dev/video11. i.e. what is the driver will be invoked when I open('/dev/video11', O_RDWR,0) in my user space code?

If I can only search within the code space, how can I find out which driver is for /dev/video11?

Is there a config file which I can look it up?

Checkout a very similar question on the Unix & Linux StackExchange.

For your device, parsing the output of this command may help.

$  udevadm info -a -n /dev/video11
