[ Upstream commite075a78119] If the of_get_named_gpio_flags call fails in vc4_hdmi_bind, we jump to the err_unprepare_hsm label. That label will then call pm_runtime_disable and put_device on the DDC device. We just retrieved the DDC device, so the latter is definitely justified. However at that point we still haven't called pm_runtime_enable, so the call to pm_runtime_disable is not supposed to be there.

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.
