[ Upstream commit e16f5e39ac ]
There were several issues with handling errors in lm3554_probe():
- Probe did not set the error code when v4l2_ctrl_handler_init() failed.
- It intermixed gotos for handling errors of v4l2_ctrl_handler_init()
and media_entity_pads_init().
- It did not set the error code for failures of v4l2_ctrl_new_custom().
- Probe did not free resources in case of failures of
atomisp_register_i2c_module().
The patch fixes all these issues.

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.
