[ Upstream commit bfecbc2cfba9b06d67d9d249c33d92e570e2fa70 ] The commitb954fa6baa("drm/msm/dpu: Refactor rm iterator") removed zero-init of the hw_ctl array, but didn't change the error condition, that checked for hw_ctl[i] being NULL. At the same time because of the early returns in case of an error dpu_encoder_phys might be left with the resources assigned in the previous state. Rework assigning of hw_pp / hw_ctl to the dpu_encoder_phys in order to make sure they are always set correctly.

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.
