commit67fe29583eupstream. IIO trigger handlers must call iio_trigger_notify_done() when done. This must be done even when an error occurred. Otherwise the trigger will be seen as busy indefinitely and the trigger handler will never be called again. The itg3200 driver neglects to call iio_trigger_notify_done() when there is an error reading the gyro data. Fix this by making sure that iio_trigger_notify_done() is included in the error exit path.

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.
