Commit 1ec49744ba ("btrfs: turn on -Wmaybe-uninitialized") exposed
that on SPARC and PA-RISC, gcc is unaware that fscrypt_setup_filename()
only returns negative error values or 0. This ultimately results in a
maybe-uninitialized warning in btrfs_lookup_dentry().
Change to only return negative error values or 0 from
fscrypt_setup_filename() at the relevant call site, and assert that no
positive error codes are returned (which would have wider implications
involving other users).

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 Restructured Text 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.
