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,
Rob

Hi Raj,
I appreciate the thought, but if you read my email closely you'll see
that I was looking for how to find if a driver is loaded into the
kernel (module or not) from within another driver's probe function.

There's not a simple answer, it depends what you are trying to achieve
(i.e. in what way is the driver dependent on the other one..)
