[ Upstream commit 69bb3520db7cecbccc9e497fc568fa5465c9d43f ]
Not all platforms have all of the four currently supported wakeup
interrupts so use the optional irq helpers when looking up interrupts to
avoid printing error messages when an optional interrupt is not found:
dwc3-qcom a6f8800.usb: error -ENXIO: IRQ hs_phy_irq not found
Fixes: a4333c3a6ba9 ("usb: dwc3: Add Qualcomm DWC3 glue driver")

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.
