(!x & y) strikes again.
Fix bitwise and boolean operations by enclosing the expression:
intcsr & (1 << NET2272_PCI_IRQ)
in parentheses, before applying the boolean operator '!'.
Notice that this code has been there since 2011. So, it would
be helpful if someone can double-check this.
This issue was detected with the help of Coccinelle.

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.
