Randy Dunlap 45e95a7bf8 kgdboc: fix return value of __setup handler 
[ Upstream commit ab818c7aa7 ]

__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) environment strings.
So return 1 from kgdboc_option_setup().

Unknown kernel command line parameters "BOOT_IMAGE=/boot/bzImage-517rc7
  kgdboc=kbd kgdbts=", will be passed to user space.

 Run /sbin/init as init process
   with arguments:
     /sbin/init
   with environment:
     HOME=/
     TERM=linux
     BOOT_IMAGE=/boot/bzImage-517rc7
     kgdboc=kbd
     kgdbts=

Fixes: 1bd54d851f ("kgdboc: Passing ekgdboc to command line causes panic")
Fixes: f2d937f3bf ("consoles: polling support, kgdboc")
