[ Upstream commit 9c7e71c97c ]
Warning was found when compiling using loongarch64-gcc 12.3.1:
$ make CFLAGS_tree-log.o=-Wmaybe-uninitialized
In file included from fs/btrfs/ctree.h:21,
from fs/btrfs/tree-log.c:12:
fs/btrfs/accessors.h: In function 'replay_one_buffer':
fs/btrfs/accessors.h:66:16: warning: 'inode_item' may be used uninitialized [-Wmaybe-uninitialized]
66 | return btrfs_get_##bits(eb, s, offsetof(type, member)); \
| ^~~~~~~~~~
fs/btrfs/tree-log.c:2803:42: note: 'inode_item' declared here
2803 | struct btrfs_inode_item *inode_item;
| ^~~~~~~~~~
Initialize the inode_item to NULL, the compiler does not seem to see the
relation between the first 'wc->log_key.type == BTRFS_INODE_ITEM_KEY'
check and the other one that also checks the replay phase.
