From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> [ Upstream commit 8b2360c7157b462c4870d447d1e65d30ef31f9aa ] __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().
