[linuxsh-dev] small bug fix

[NIIBE Y. <gn...@m1...>]

This is not an issue actually, because all the call are aligned.
But a bug is a bug, is a bug.

	* arch/sh/mm/cache-sh4.c (__flush_wback_region): Fix bug of
	expression of END.
	(__flush_purge_region): Likewise.
	(__flush_invalidate_region): Likewise.
