3.16.7-ckt22 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Geert Uytterhoeven <ge...@linux-m68k.org>
commit cf89752645e47d86ba8a4157f4b121fcb33434c5 upstream.
fs/cachefiles/rdwr.c: In function ‘cachefiles_write_page’:
fs/cachefiles/rdwr.c:882: warning: ‘ret’ may be used uninitialized in
this function
If the jump to label "error" is taken, "ret" will indeed be
uninitialized, and random stack data may be printed by the debug code.
Fixes: 102f4d900c9c8f5e ("FS-Cache: Handle a write to the page immediately
beyond the EOF marker")
