Pavel Skripkin 7163014d7d media: go7007: remove redundant initialization 
[ Upstream commit 6f5885a7750545973bf1a942d2f0f129aef0aa06 ]

In go7007_alloc() kzalloc() is used for struct go7007
allocation. It means that there is no need in zeroing
any members, because kzalloc will take care of it.

Removing these reduntant initialization steps increases
execution speed a lot:

	Before:
		+ 86.802 us   |    go7007_alloc();
	After:
		+ 29.595 us   |    go7007_alloc();

Fixes: 866b8695d6 ("Staging: add the go7007 video driver")

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.
