Btrfs: fix compiler warning in file.c
Tsutomu Itoh [Wed, 30 Mar 2011 00:57:23 +0000 (00:57 +0000)]
While compiling Btrfs, I got following messages:

CC [M] fs/btrfs/file.o
fs/btrfs/file.c: In function '__btrfs_buffered_write':
fs/btrfs/file.c:909: warning: 'ret' may be used uninitialized in this function
CC [M] fs/btrfs/tree-defrag.o

This patch fixes compiler warning.
