Nuno Sá b600bd7eb3 iio: adis: do not disabe IRQs in 'adis_init()' 
With commit ecb010d441 ("iio: imu: adis: Refactor adis_initial_startup")
we are doing a HW or SW reset to the device which means that we'll get
the default state of the data ready pin (which is enabled). Hence there's
no point in disabling the IRQ in the init function. Moreover, this
function is intended to initialize internal data structures and not
really do anything on the device.

As a result of this, some devices were left with the data ready pin enabled
after probe which was not the desired behavior. Thus, we move the call to
'adis_enable_irq()' to the initial startup function where it makes more
sense for it to be.

Note that for devices that cannot mask/unmask the pin, it makes no sense
to call the function at this point since the IRQ should not have been
yet requested. This will be improved in a follow up change.

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.
