[ Upstream commit dc18836435e7f8dda019db2c618c69194933157f ] The multiple BWMONv4 instances available on the X1E80100 SoC use the same interrupt number. Mark them are shared to allow for re-use across instances. Using IRQF_SHARED coupled with devm_request_threaded_irq implies that the irq can still trigger during/after bwmon_remove due to other active bwmon instances. Handle this race by relying on bwmon_disable to disable the interrupt and coupled with explicit request/free irqs.

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.
