Without full context that error looks odd. Make sure you are not
trying to build "linux-xlnx" as a dependency or directly on the
command line, instead use 'virtual/kernel'.

There might also be something else going on to cause the issue you are
seeing. To clarify how to use the linux-xlnx-dev recipe the way you
are after you will want to make your SRCREV setting very specific.
Also if you want to use a branch other than master-next.

SRCREV_pn-linux-xlnx-dev = "<REV HERE>"
KBRANCH_pn-linux-xlnx-dev = "<BRANCH HERE>"
PREFERRED_PROVIDER_virtual/kernel = "linux-xlnx-dev"

One thing to note is that the commit must exist on a branch otherwise
the git fetcher will not be able to retrieve the commit id. (some of
the tags in the linux-xlnx repo are orphaned/not on a branch so be
careful)
