driver core: dd: fix return value of __setup handler
When "driver_async_probe=nulltty" is used on the kernel boot command line,
it causes an Unknown parameter message and the string is added to init's
environment strings, polluting them.
Unknown kernel command line parameters "BOOT_IMAGE=/boot/bzImage-517rc6
driver_async_probe=nulltty", 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-517rc6
driver_async_probe=nulltty
Change the return value of the __setup function to 1 to indicate
that the __setup option has been handled.
