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.
