Testing to see if a driver is loaded

Greetings once again,

I was wondering if there is a simple way to test if a driver is loaded
from within another driver's probe? I have one driver that depends on
another. I see several *_find_device functions in
include/linux/device.h. I haven't found a "find driver" nor an
arbitrary way of doing that.

Thanks for any guidance,
