drivers/misc/c2port/c2port-duramar2150.c: checking for NULL instead of IS_ERR()
c2port_device_register() never returns NULL, it uses error pointers. Link: http://lkml.kernel.org/r/20170412083321.GC3250@mwanda Fixes: 65131cd52b9e ("c2port: add c2port support for Eurotech Duramar 2150") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Rodolfo Giometti <giometti@linux.it> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
