Douglas Anderson 6943b83972 clk: rockchip: Don't yell about bad mmc phases when getting
At boot time, my rk3288-veyron devices yell with 8 lines that look
like this:
  [    0.000000] rockchip_mmc_get_phase: invalid clk rate

This is because the clock framework at clk_register() time tries to
get the phase but we don't have a parent yet.

While the errors appear to be harmless they are still ugly and, in
general, we don't want yells like this in the log unless they are
important.

There's no real reason to be yelling here.  We can still return
-EINVAL to indicate that the phase makes no sense without a parent.
If someone really tries to do tuning and the clock is reported as 0
then we'll see the yells in rockchip_mmc_set_phase().

Fixes: 4bf59902b5 ("clk: rockchip: Prevent calculating mmc phase if clock rate is zero")

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.
