commit a254a0e4093fce8c832414a83940736067eed515 upstream. Now that have_bytes is never modified, we can simplify this function. First, we move the check for negative entropy_count to be first. That ensures that subsequent reads of this will be non-negative. Then, have_bytes and ibytes can be folded into their one use site in the min_t() 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.
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.
