Use devm_kzalloc() to allocate the sensor data struct. It is always free-ed as the last step of probe-error-exit or remove, so it can be devm-managed. This will make unwinding things easier when support is added to the ov2680 code to use standard GPIO APIs instead of the custom atomisp_gmin code. This also allows dropping the out_free label and use direct return on errors. This may seem like a functional change since the out_free label also did a v4l2_device_unregister_subdev() but at the 2 changed returns the device is not registered yet, so that always is a no-op and can be dropped.

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.
