Dan Carpenter fd8d6b04de drm/bridge: nxp-ptn3460: simplify some error checking 
commit 28d3d06966 upstream.

The i2c_master_send/recv() functions return negative error codes or
they return "len" on success.  So the error handling here can be written
as just normal checks for "if (ret < 0) return ret;".  No need to
complicate things.

Btw, in this code the "len" parameter can never be zero, but even if
it were, then I feel like this would still be the best way to write it.

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.
