Changes in v2:
-alps_is_valid_package_v7: switch to using a switch-case
-alps_check_valid_firmware_id: fix to not always return true
Thank you for whipping the update so quickly.

+static void alps_get_finger_coordinate_v7(struct input_mt_pos *mt,
+ unsigned char *pkt,
+ unsigned char pkt_id)
+{
+ mt[0].x = ((pkt[2] & 0x80) << 4);
+ mt[0].x |= ((pkt[2] & 0x3F) << 5);
+ mt[0].x |= ((pkt[3] & 0x30) >> 1);
+ mt[0].x |= (pkt[3] & 0x07);
+ mt[0].y = (pkt[1] << 3) | (pkt[0] & 0x07);
+
+ mt[1].x = ((pkt[3] & 0x80) << 4);
+ mt[1].x |= ((pkt[4] & 0x80) << 3);
+ mt[1].x |= ((pkt[4] & 0x3F) << 4);
+ mt[1].y = ((pkt[5] & 0x80) << 3);
+ mt[1].y |= ((pkt[5] & 0x3F) << 4);
+
+ if (pkt_id == V7_PACKET_ID_TWO) {
+ mt[1].x &= ~0x000F;
+ mt[1].y |= 0x000F;
+ } else if (pkt_id == V7_PACKET_ID_MULTI) {
+ mt[1].x &= ~0x003F;
+ mt[1].y &= ~0x0020;
+ mt[1].y |= ((pkt[4] & 0x02) << 4);
+ mt[1].y |= 0x001F;
+ } else if (pkt_id == V7_PACKET_ID_NEW) {
+ mt[1].x &= ~0x003F;
+ mt[1].x |= (pkt[0] & 0x20);
+ mt[1].y |= 0x000F;
+ }
I took the liberty of changing the above to another switch/case...
+static bool alps_check_valid_firmware_id(unsigned char id[])
+{
+ if (id[0] == 0x73)
+ return true;
+
+ if (id[0] == 0x88 &&
+ (id[1] == 0x07 || id[1] == 0x08 ||
+ (id[1] & 0xf0) == 0xb0 || (id[1] & 0xf0) == 0xc0))
And split this condition into 1 line per id[1] check...
+ return true;
+
+ return false;
+}
+
And applied and pushed out everything.
Ok, thanks.
Regards,
Hans
