If you compile with:
CONFIG_HID_HOLTEK=m
CONFIG_HOLTEK_FF is not set

You get the following warning:
WARNING: modpost: missing MODULE_LICENSE() in drivers/hid/hid-holtekff.o
see include/linux/module.h for more information

Fix this by moving the module info out of the #ifdef CONFIG_HOLTEK_FF
block and into the un-guarded part of the file.
