Summary
cxl: fix possible null-ptr-deref in cxl_pci_init_afu|adapter()
Details

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

cxl: fix possible null-ptr-deref in cxlpciinit_afu|adapter()

If deviceregister() fails in cxlpciafu|adapter(), the device is not added, deviceunregister() can not be called in the error path, otherwise it will cause a null-ptr-deref because of removing not added device.

As comment of deviceregister() says, it should use putdevice() to give up the reference in the error path. So split deviceunregister() into devicedel() and put_device(), then goes to put dev when register fails.
