commit 27b2ed5b6d53cd62fc61c3f259ae52f5cac23b66 upstream.
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.
Fixes:

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.
