[ Upstream commit5e05be7826] If the drm/msm init code gets an error during output modeset initialisation, the kernel will report an error regarding DRM memory manager not being clean during shutdown. This is because msm_dsi_modeset_init() allocates a piece of GEM memory for the TX buffer, but destruction of the buffer happens only at msm_dsi_host_destroy(), which is called during DSI driver's remove() time, much later than the DRM MM shutdown. To solve this issue, move the TX buffer destruction to dsi_unbind(), so that the buffer is destructed at the correct time. Note, we also have to store a reference to the address space, because priv->kms->aspace is cleared before components are unbound.

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.
