From: Greg Kroah-Hartman

commit 8c5477e8046ca139bac250386c08453da37ec1ae upstream.

Kernel build warns:
'sanitize_boot_params' defined but not used [-Wunused-function]

at below files:

That's becausethey each include misc.h which includes a definition of
sanitize_boot_params() via bootparam_utils.h.

Remove the inclusion from misc.h and have the c file including
bootparam_utils.h directly.
