The handling of kfifo_out() errors in read functions obscures any error. The error condition should never occur but, while a ret is set to -EIO, it is subsequently ignored and the read functions instead return the number of bytes copied to that point, potentially masking the fact that any error occurred. Log a warning and return -EIO in the case of a kfifo_out() error to make it clear something very odd is going on here.

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.
