Subject: Re: [net-next,PATCH 1/2] net: stmmac: dwmac-stm32: Add test to verify

I think it would be better to add fullstop (.) here , and then continue:

If ETHCK is unused, the ETHCK frequency is 0 Hz and validation fails. It 
makes no sense to validate unused ETHCK, so skip the validation.

With the commit message updated a bit
