[ Upstream commit d3429178ee51dd7155445d15a5ab87a45fae3c73 ] When probing the I2C master, disable SMBus interrupts to prevent storms caused by broken firmware mis-configuring IC_SMBUS=1; the handler never services them and a mis-configured SMBUS Master extend-clock timeout or SMBUS Slave extend-clock timeout can flood the CPU.

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.
