This is a note to let you know that I've just added the patch titled
Revert "scsi: ufs: fix a missing check of devm_reset_control_get"
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.

From: Greg Kroah-Hartman gregkh@linuxfoundation.org Date: Mon, 3 May 2021 13:56:57 +0200 Subject: Revert "scsi: ufs: fix a missing check of devm_reset_control_get"
This reverts commit 63a06181d7ce169d09843645c50fea1901bc9f0a.
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 is incorrect, it does not properly clean up on the error path, so I'll keep the revert and fix it up properly with a follow-on patch.
