You may mention those links in the cover letter, since mediafire links are
unlikely to last, better no mentioning them here. The version is enough.

The commit where the issue is introduced is actually
Fixes: 738f66d3211d ("clk: gxbb: add AmLogic GXBB clk controller driver") 

Yes there has been a rework afterward, but the problem you are fixing originate
from that commit.
