patch "Revert "serial: mvebu-uart: Fix to avoid a potential NULL pointer" added to char-misc-linus

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

Revert "serial: mvebu-uart: Fix to avoid a potential NULL pointer

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 "serial: mvebu-uart: Fix to avoid a potential NULL pointer
dereference"

This reverts commit 32f47179833b63de72427131169809065db6745e.

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 not be needed at all as the change was useless because this function can only be called when of_match_device matched on something. So it should be reverted.
