Although convert_initialized_extent() can potentially return an error code with a negative value, its returned value is assigned to an unsigned variable containing a block count in ext4_ext_map_blocks() and then returned to that function's caller. The code currently works, though the way this happens is obscure. The code would be more readable if it followed the error handling convention used elsewhere in ext4_ext_map_blocks(). This patch does not address any known test failure or bug report - it's simply a cleanup. It also addresses a nearby coding standard issue.

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.
