>> WARNING: modpost: vmlinux.o(.init.literal+0xec14): Section mismatch in reference from the (unknown reference) (unknown) to the (unknown reference) .exit.text:(unknown)
The (unknown reference) __init (unknown) references
a (unknown reference) __exit (unknown).
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __exit annotation of
(unknown) so it may be used outside an exit section.
