The commit message should explain why this is needed rather than just state what is being done. For example, something along the lines of The three UFS reference clocks gcc_ufs_ref_clkref_clk, gcc_ufs_card_clkref_clk and gcc_ufs_1_card_clkref_clk are all sourced from CXO.

I think it's ok to keep that Link if it was intended as a reference to the discussions leading up to this patch. There can be more than one Link tag, and this one is more in line with how Linus thinks they should be used than the ones added by tooling such as b4 when applying. Johan
