We never really look at the 'ret' local variable in these functions, so let's remove it to make way for shorter and simpler code. Furthermore, we can shorten some lines by adding two local variables for the SE and the message length so that everything fits in 80 columns and testing the 'dma_buf' local variable in lieu of the 'mode' local variable. And kernel style is to leave the return statement by itself, detached from the rest of the function.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
