[ Upstream commitbc341a1a98] If alert handling is broken, interrupts are disabled after an alert and re-enabled after the alert clears. However, if there is an interrupt handler, this does not apply if alerts were originally disabled and enabled when the driver was loaded. In that case, interrupts will stay disabled after an alert was handled though the alert handler even after the alert condition clears. Address the situation by always re-enabling interrupts after the alert condition clears if there is an interrupt handler.

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.
