[ Upstream commit1750069567] In dwc3_qcom_acpi_register_core(), the driver neglects to check the result of platform_get_irq()'s call and blithely assigns the negative error codes to the allocated child device's IRQ resource and then passing this resource to platform_device_add_resources() and later causing dwc3_otg_get_irq() to fail anyway. Stop calling platform_device_add_resources() with the invalid IRQ #s, so that there's less complexity in the IRQ error checking.

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.
