| |
'packet_id' is used for checking sequence whether in order, it need be static variable independent from sur40_poll().
The related warning (with allmodconfig under hexagon):
drivers/input/touchscreen/sur40.c: In function 'sur40_poll': drivers/input/touchscreen/sur40.c:297:6: warning: 'packet_id' may be used uninitialized in this function [-Wuninitialized]
