[ Upstream commit cc8294ec4738d25e2bb2d71f7d82a9bf7f4a157b ]
__setup() handlers should return 1 if the command line option is handled and 0 if not (or maybe never return 0; doing so just pollutes init's environment with strings that are not init arguments/parameters).
Return 1 from aha152x_setup() to indicate that the boot option has been handled.
