patch "Revert "media: rcar_drif: fix a memory disclosure"" added to char-misc-linus

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

Revert "media: rcar_drif: fix a memory disclosure"

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 "media: rcar_drif: fix a memory disclosure"

This reverts commit d39083234c60519724c6ed59509a2129fd2aed41.

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, it was determined that this commit is not needed at all as the media core already prevents memory disclosure on this codepath, so just drop the extra memset happening here.
