The ingenic remoteproc driver requests its IRQ and then immediately disables it. The disable is necessary since irq_request() normally enables the IRQ. But there is a new flag IRQF_NO_AUTOEN that when specified keeps the IRQ disabled. Use this new flag rather than calling disable_irq(). This slightly reduce the boilerplate code and also avoids a theoretical race condition where the IRQ could fire between irq_request() and disable_irq().

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.
