Summary
net: qrtr: start MHI channel after endpoit creation
Details

In the Linux kernel, the following vulnerability has been resolved:

net: qrtr: start MHI channel after endpoit creation

MHI channel may generates event/interrupt right after enabling. It may leads to 2 race conditions issues.

1) Such event may be dropped by qcommhiqrtrdlcallback() at check:

if (!qdev || mhi_res->transaction_status)
    return;

Because devsetdrvdata(&mhi_dev->dev, qdev) may be not performed at this moment. In this situation qrtr-ns will be unable to enumerate

services in device.

2) Such event may come at the moment after devsetdrvdata() and before qrtrendpointregister(). In this case kernel will panic with accessing wrong pointer at qcommhiqrtrdlcallback():

rc = qrtr_endpoint_post(&qdev->ep, mhi_res->buf_addr,
            mhi_res->bytes_xferd);

Because endpoint is not created yet.

So move mhipreparefortransferautoqueue after endpoint creation to fix it.
