Dan Carpenter 77516d25f5 rsxx: Return -EFAULT if copy_to_user() fails The copy_to_user() function returns the number of bytes remaining but we want to return -EFAULT to the user if it can't complete the copy. The "st" variable only holds zero on success or negative error codes on failure so the type should be int. Fixes: `36f988e978` ("rsxx: Adding in debugfs entries.")

README

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.
