commit 6943b839721ad4a31ad2bacf6e71b21f2dfe3134 upstream.
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: 4bf59902b500 ("clk: rockchip: Prevent calculating mmc phase if clock rate is zero")

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.
