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

serial: 8250_pci: Make PCI class test non fatal

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-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: Andy Shevchenko andriy.shevchenko@linux.intel.com Date: Thu, 24 Jan 2019 23:51:21 +0200 Subject: serial: 8250_pci: Make PCI class test non fatal

As has been reported the National Instruments serial cards have broken PCI class.

The commit 7d8905d06405

("serial: 8250_pci: Enable device after we check black list")

made the PCI class check mandatory for the case when device is listed in a quirk list.

Make PCI class test non fatal to allow broken card be enumerated.
