Marek Behún 5c0d20a968 leds: lm36274: use platform device as parent of LED
Instead of registering LED under the MFD device, this driver sets the
parent of the LED it is registering to the parent of the MFD device (the
I2C client device).

Because of this we cannot use devres for LED registration, since it can
result in use-after-free, see commit
a0972fff09 ("leds: lm36274: fix use-after-free on unbind").

The only other in-tree driver that also registers under the MFD device
(drivers/regulator/lm363x-regulator.c) sets the parent to the MFD
device.

Set the parent of this LED to the MFD device, instead of the I2C client
device.

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.
