Krzysztof Kozlowski 10eecb592a mfd: max77620: Fix potential IRQ chip conflict when probing two devices 
commit 2bac49bad1 upstream.

MAX77620 is most likely always a single device on the board, however
nothing stops board designers to have two of them, thus same device
driver could probe twice. Or user could manually try to probing second
time.

Device driver is not ready for that case, because it allocates
statically 'struct regmap_irq_chip' as non-const and stores during
probe in 'irq_drv_data' member a pointer to per-probe state
container ('struct max77620_chip').  devm_regmap_add_irq_chip() does not
make a copy of 'struct regmap_irq_chip' but store the pointer.

Second probe - either successful or failure - would overwrite the
'irq_drv_data' from previous device probe, so interrupts would be
executed in a wrong context.

README 

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.
