commit ef5f5e7b6f73f79538892a8be3a3bee2342acc9f upstream.
When multiple ODR switch happens during FIFO off, the change could
not be taken into account if you get back to previous FIFO on value.
For example, if you run sensor buffer at 50Hz, stop, change to
200Hz, then back to 50Hz and restart buffer, data will be timestamped
at 200Hz. This due to testing against mult and not new_mult.
To prevent this, let's just run apply_odr automatically when FIFO is
off. It will also simplify driver code.
Update inv_mpu6050 and inv_icm42600 to delete now useless apply_odr.

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.
