[PATCH] staging/atomisp: make six local functions static to appease sparse

[PATCH] staging/atomisp: make six local functions static to appease sparse

[Muhammad Falak R Wani]

The functions __bo_alloc, __bo_search_and_remove_from_free_rbtree,
__bo_search_by_addr, __bo_search_by_addr_in_range, __bo_break_up and
__bo_merge  are local to the source and do not need to be in the global
scope, so make them static.

Cleans up sparse warnings:

warning: symbol '__bo_alloc' was not declared. Should it be static?
warning: symbol '__bo_search_and_remove_from_free_rbtree' was not declared. Should it be static?
warning: symbol '__bo_search_by_addr' was not declared. Should it be static?
warning: symbol '__bo_search_by_addr_in_range' was not declared. Should it be static?
warning: symbol '__bo_break_up' was not declared. Should it be static?
warning: symbol '__bo_merge' was not declared. Should it be static?
