Tony Lindgren 883b3b6567 i2c: omap: Fix error handling for clk_get()
Otherwise we can get the following if the fck alias is missing:

Unable to handle kernel paging request at virtual address fffffffe
...
PC is at clk_get_rate+0x8/0x10

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
