This patch is not enough. ALPS_DUALPOINT flag can be removed also 
in function alps_hw_init_rushmore_v3() which is called from 
alps_init() but not from alps_detect(). So this patch does not 
have to set correct name in alps_detect() based on ALPS_DUALPOINT 
flag. My original patch set name in alps_init() after hw_init() 
which handled also this problem...
