commit27b2ed5b6dupstream. Smatch reports: drivers/iio/adc/mxs-lradc-adc.c:766 mxs_lradc_adc_probe() warn: missing unwind goto? the order of three init operation: 1.mxs_lradc_adc_trigger_init 2.iio_triggered_buffer_setup 3.mxs_lradc_adc_hw_init thus, the order of three cleanup operation should be: 1.mxs_lradc_adc_hw_stop 2.iio_triggered_buffer_cleanup 3.mxs_lradc_adc_trigger_remove we exchange the order of two cleanup operations, introducing the following differences: 1.if mxs_lradc_adc_trigger_init fails, returns directly; 2.if trigger_init succeeds but iio_triggered_buffer_setup fails, goto err_trig and remove the trigger. In addition, we also reorder the unwind that goes on in the remove() callback to match the new ordering.

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.
