Converting the WARN_ON() to a dev_dbg() message in i2c_dw_clk_rate(). That removes the need to supply a dummy implementation for the callback (or alternatively a dummy clk device) when the fallback path is preferred where the existing values already in the clock registers are used - when a firmware has programmed the clock registers. The fallback path was introduced in commit 4fec76e0985c ("i2c: designware: Fix wrong setting for {ss,fs,hs}_{h,l}cnt registers").
