This is a note to let you know that I've just added the patch titled
serial: 8250_pci: Add support for Pericom PI7C9X795[1248]
to my tty git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
in the tty-next 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 also be merged in the next major kernel release

Subject: serial: 8250_pci: Add support for Pericom PI7C9X795[1248]
Pericom PI7C9X795[1248] are Uno/Dual/Quad/Octal UART devices, this
patch enables them, also defines PCI_VENDOR_ID_PERICOM here.
