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

mei: me: add tiger lake point device ids for H platforms.

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: mei: me: add tiger lake point device ids for H platforms.

Add Tiger Lake device ids H for HECI1.
TGH_H is also used in Tatlow SPS platform we need to disable the mei interface there.
