Subject[PATCH] at86rf230: fix build warning
Message-ID<q7t7Y-6eG-11@gated-at.bofh.it>
e616a00ce786 ("drivers/net/ieee802154/at86rf230.c: seq_printf() now returns NULL")
has removed the usage of the integer "ret" but missed removing the
variable. And we were getting a build warning about "unused variable".

Fixes: e616a00ce786 ("drivers/net/ieee802154/at86rf230.c: seq_printf() now returns NULL")

Please drop this patch. This was against a temporary fix by Stephen on
linux-next. The commit is not availble now.
