Brian Norris 32a267e9c0 drm/panel: innolux-p079zca: Delete panel on attach() failure
If we fail to attach (e.g., because 1 of 2 dual-DSI controllers aren't
ready), we leave a dangling drm_panel reference to freed memory. Clean
that up on failure.

This problem exists since the driver's introduction, but is especially
relevant after refactored for dual-DSI variants.

Fixes: 14c8f2e9f8 ("drm/panel: add Innolux P079ZCA panel driver")
Fixes: 7ad4e4636c ("drm/panel: p079zca: Refactor panel driver to support multiple panels")

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.
