Yang Yingliang ef054e345e media: si470x-i2c: fix possible memory leak in si470x_i2c_probe() 
n the 'radio->hdl.error' error handling, ctrl handler allocated by
v4l2_ctrl_new_std() does not released, and caused memory leak as
follows:

unreferenced object 0xffff888033d54200 (size 256):
  comm "i2c-si470x-19", pid 909, jiffies 4294914203 (age 8.072s)
  hex dump (first 32 bytes):

Fix the error handling path to avoid memory leak.

README

README 

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.
