Dan Carpenter cdcba752a3 accel/qaic: Fix a leak in map_user_pages() 
commit 73274c33d9 upstream.

If get_user_pages_fast() allocates some pages but not as many as we
wanted, then the current code leaks those pages.  Call put_page() on
the pages before returning.

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.
