Subject: [PATCH] jffs2: mark __jffs2_dbg_superblock_counts() static

From: Arnd Bergmann <arnd@...db.de>

This function is only called locally and does not need to be
global. Since there is no external prototype, gcc warns about
the non-static definition:

fs/jffs2/debug.c:160:6: error: no previous prototype for '__jffs2_dbg_superblock_counts' [-Werror=missing-prototypes]
