[Xenomai-help] Passing data from device init to open function

[Johan Borkhuis <j.borkhuis@domain.hid>]

Hello,

I am facing the following problem. During device initialization I am 
filling a structure with device specific data. This structure is 
provided to the Linux driver using pci_set_drvdata. Now I want my 
Xenomai driver to have access to this data as well.
I am planning to use the dev_private area for this, and have it contain 
a pointer to the same structure. The rtdm_dev_context structure is only 
available after the open call and not in the device init function. So I 
am searching for a safe way to transfer data from the device init 
function to the open function.

Is there a way to transfer data from the device init function to the 
open (or other) functions in such a way that it is possible to have 
multiple devices that can be opened multiple times?

Kind regards,
