Subject: ARM: 9187/1: JIVE: fix return value of __setup handler

From: Randy Dunlap <rdunlap@infradead.org>

commit 8b2360c7157b462c4870d447d1e65d30ef31f9aa upstream.

__setup() handlers should return 1 to obsolete_checksetup() in
init/main.c to indicate that the boot option has been handled.
A return of 0 causes the boot option/value to be listed as an Unknown
kernel parameter and added to init's (limited) argument or environment
strings. Also, error return codes don't mean anything to
obsolete_checksetup() -- only non-zero (usually 1) or zero.
So return 1 from jive_mtdset().
