msmgpio irqchip was not using return value of irq_set_irq_wake() callback since previously GIC-v3 irqchip neither had IRQCHIP_SKIP_SET_WAKE flag nor it implemented .irq_set_wake callback. This lead to irq_set_irq_wake() return error -ENXIO. However from 'commit4110b5cbb0("irqchip/gic-v3: Allow interrupt to be configured as wake-up sources")' GIC irqchip has IRQCHIP_SKIP_SET_WAKE flag. Use return value from irq_set_irq_wake() and irq_chip_set_wake_parent() instead of always returning success.

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.
