Abdun Nihaal 3eb2bc1009 fbdev: hecubafb: fix potential memory leak in hecubafb_probe() 
commit cbef2a305a upstream.

The memory allocated for pagerefs in fb_deferred_io_init() is not freed
on the error path. Fix it by calling fb_deferred_io_cleanup().

Fixes: 56c134f7f1 ("fbdev: Track deferred-I/O pages in pageref struct")

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.
