patch "serial: liteuart: Fix NULL pointer dereference in ->remove()" added to tty-linus

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

    serial: liteuart: Fix NULL pointer dereference in ->remove()

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.

Subject: serial: liteuart: Fix NULL pointer dereference in ->remove()

drvdata has to be set in _probe() - otherwise platform_get_drvdata() causes null pointer dereference BUG in _remove().
