Pavel Skripkin eac7d9f47a staging: r8188eu: add error handling of rtw_read8
[ Upstream commit 857fe9e5efc09833fe1110e99d8baba954a86abb ]

rtw_read8() reads data from device via USB API which may fail. In case
of any failure previous code returned stack data to callers, which is
wrong.

Fix it by changing rtw_read8() prototype and prevent caller from
touching random stack data

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.
