Subject: [PATCH] Remove errno declaration in drivers/sbus/char/envctrl.c

errno is already declarded in linux/errno.h:

drivers/sbus/char/envctrl.c:40: error: static declaration of 'errno' follows non-static declaration
include/linux/unistd.h:4: error: previous declaration of 'errno' was here
make[3]: *** [drivers/sbus/char/envctrl.o] Error 1
make[2]: *** [drivers/sbus/char] Error 2
make[1]: *** [drivers/sbus] Error 2
make: *** [drivers] Error 2


Moreover errno isn't used in this file at all so the following patch
(against latest git tree) just removes it (kernel compiles fine).
