From 7975a9b7323d5a47e5b651bac810f3271e7156df Mon Sep 17 00:00:00 2001
From: Joel Stanley <joel@jms.id.au>

Subject: [PATCH] drivers/sbus/char/envctrl.c: ignore orderly_poweroff return
value
orderly_poweroff() unconditionally returns 0, so remove the dead code that
checks the return value.
A future patch will change the return type to void.
