Mark Brown 4c22e09c65 spi: omap2-mcspi: Correctly handle devm_clk_get_optional() errors 
[ Upstream commit a07eb4f67e ]

devm_clk_get_optional() returns NULL for missing clocks and a PTR_ERR()
if there is a clock but we fail to get it, but currently we only handle
the latter case and do so as though the clock was missing.  If we get an
error back we should handle that as an error since the clock exists but
we failed to get it, if we get NULL then the clock doesn't exist and we
should handle that.

Fixes: 4c6ac5446d ("spi: omap2-mcspi: Fix the IS_ERR() bug for devm_clk_get_optional_enabled()")

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 reStructuredText 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.
