Subject[ 36/37] Input: bcm5974 - set BUTTONPAD property
Date
3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jussi Pakkanen <jussi.pakkanen@canonical.com>

commit 52965cc012f7a3cf35f06485ec275ebf3b3fddae upstream.

Some bcm5974 trackpads have a physical button beneath the physical surface.
This patch sets the property bit so user space applications can detect the
trackpad type and act accordingly.
