Linux kernel source tree

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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
