mm: remove redundant K() macro definition
Patch series "cleanup with helper macro K()". Use helper macro K() to improve code readability. No functional modification involved. Remove redundant K() macro definition. This patch (of 7): Since commit eb8589b4f8c1 ("mm: move mem_init_print_info() to mm_init.c"), the K() macro definition has been moved to mm/internal.h. Therefore, the definitions in mm/memcontrol.c, mm/backing-dev.c and mm/oom_kill.c are redundant. Drop redundant definitions.
