Hi

after eliminate  the fmh_gpibi (error: implicit declaration of function 
‘of_find_node_by_path’),
the linux-gpib-4.2.0 do compile without error.

May  1 14:59:28 mcp21 kernel: Linux-GPIB 4.2.0 Driver

Now i receive on the first ibwrt-command an error:

returnvalue=8100  iberr=0  errno=25

Any idea?

Kind regards
