#70 closed defect (fixed)

pcilib should be able to be called concurrently

Description

This morning, I tried to call the control application on iss-suren with the camera connected. However, the system completely crashed and could only be rebooted. Problem was, that Michele ran control the whole night and it was still running.

Not being able to call pcilib_open() twice is a serious issue and IMHO not tolerable. Moreover, it should be pretty easy to fix in the driver/pcilib abstraction.

Yes, it is easy to fix it in pcilib, but there is few reasons why it should be done at the kernel level. I'll need some time for that, but it is in the top of my to do list.

Some locking added to prevent multiple grabbing operations. pcilib r292 and ipecamera r265.
