patch "Revert "net: stmicro: fix a missing check of clk_prepare"" added to char-misc-linus

This is a note to let you know that I've just added the patch titled

Revert "net: stmicro: fix a missing check of clk_prepare"

to my char-misc git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: Revert "net: stmicro: fix a missing check of clk_prepare"

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.
