neo: Remove a bogus NULL check
Julia Lawall found an un-needed check in the neo driver. Her patch moves the check to cover the code dereferencing it, however it cannot be NULL anyway so remove the NULL check instead. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
