The quirk code currently detects all compatible I2C chips with a shared IRQ line on all I2C busses, adds them into a list, and registers a bus notifier. For every chip for which the bus notifier triggers, the quirk code performs I2C transfer on that I2C bus for all addresses in the list. The problem is that this may generate transfers to non-existing chips on systems with multiple I2C busses. This patch adds a check to verify that the I2C bus to which the chip with shared IRQ is attached to matches the I2C bus of the chip which triggered the bus notifier and only starts the I2C transfer if they match.

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.
