Thomas Fourier 91f08ec6a9 auxdisplay: arm-charlcd: fix release_mem_region() size
[ Upstream commit b5c23a4d29 ]

It seems like, after the request_mem_region(), the corresponding
release_mem_region() must take the same size. This was done
in (now removed due to previous refactoring) charlcd_remove()
but not in the error path in charlcd_probe().

Fixes: ce8962455e ("ARM: 6214/2: driver for the character LCD found in ARM refdesigns")

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 reStructuredText 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.
