CVE-2022-49824

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

ata: libata-transport: fix error handling in ata_tlink_add()

In ata_tlink_add(), the return value of transport_add_device() is
not checked. As a result, it causes null-ptr-deref while removing
the module, because transport_remove_device() is called to remove
the device that was not added.

Unable to handle kernel NULL pointer dereference at virtual address 00000000000000d0

Fix this by checking and handling return value of transport_add_device()
in ata_tlink_add().
