kgdbts: fix return value of __setup handler
[ Upstream commit 96c9e802c64014a7716865332d732cc9c7f24593 ]
__setup() handlers should return 1 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 kgdbts_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=
