From: Arnd Bergmann <arnd@arndb.de>

When SMBUS is disabled, this is never referenced, causing a W=1 warning:

drivers/input/mouse/synaptics.c:164:27: error: 'smbus_pnp_ids' defined but not used [-Werror=unused-const-variable=]

Hide the array behind the same #ifdef as the code referencing it.

Fixes: e839ffab0289 ("Input: synaptics - add support for Intertouch devices")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
