Merge series "ASoC: rt5682: Use clk APIs better" from Stephen Boyd <swboyd@chromium.org>:

This patch series drops a printk message down to dev_dbg() because it
was noisy and then migrates this driver to use clk_hw based APIs instead
of clk based APIs because this device is a clk provider, not a clk
consumer. I've only lightly tested the last two patches but I don't have
all combinations of clks for this device.

Stephen Boyd (3):
  ASoC: rt5682: Use dev_dbg() in rt5682_clk_check()
  ASoC: rt5682: Drop usage of __clk_get_name()
  ASoC: rt5682: Use clk_hw based APIs for registration
