Revert "net: stmicro: fix a missing check of clk_prepare"
commit bee1b0511844c8c79fccf1f2b13472393b6b91f7 upstream.
This reverts commit f86a3b83833e7cfe558ca4d70b64ebc48903efec.
Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.
Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted. It will be fixed up "correctly" in a
later kernel change.
The original commit causes a memory leak when it is trying to claim it
is properly handling errors. Revert this change and fix it up properly
in a follow-on commit.
