platform_device.dev.release not getting called under X Windows

[kaustav.majumdar at wipro.com]

Hi all,

We are developing a device driver for a PCMCIA based USB Host
Controller.
We are facing an issue in the operation of the driver under X Windows.

In the PCMCIA client driver, we register a platform device.
Through this platform device, we are passing the resources to the Host
Controller Driver.
The HCD is using these resources for driving the Host Controller.

The issue arises for the following situation under X Windows.
1. Insert a USB mass storage device
2. Mount the device.
3. While transfer is in progress, remove the PC card.

In this situation, we have noted that the platform_device.dev.release
function is not getting called.
If we do not mount the device, then the release function is getting
called.
Can anyone please tell why this may be happening?

When we operate from console, we are not facing the issue.
In that case the release function is getting called properly.
Then does the issue have anything to do with X Windows?

Looking forward to your suggestions

Thank you,
With Regards,
Kaustav Majumdar
