The commit5a9d50150c("drm/msm/dpu: shift IRQ indices by 1") shifted IRQ indices by 1, making 'NO_IRQ' to be 0 rather than -1 (and allowing to skip the definition if the IRQ is not present). Several platform files were sketched before that commit, but got applied afterwards. As such, they inherited historical (and currently incorrect) setting of .intr_tear_rd_ptr = -1 for 'NO_IRQ' value. Drop that setting for all the affected platforms.

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.
