Subject: [PATCH] Input: synaptics - fix compile warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Move synaptics_invert_y() inside CONFIG_MOUSE_PS2_SYNAPTICS to get rid of
a compile warning when we don't select synaptics support.
drivers/input/mouse/synaptics.c:53:12: warning: ‘synaptics_invert_y’ defined but not used [-Wunused-function]
