-Subject: [PATCH] clk: rockchip: Don't yell about bad mmc phases when getting
-Date: Fri, 3 May 2019 14:22:08 -0700
-
-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")
