Yup,
checkpatch output is definitely a mix of automated
semi-competence and brain-deadness.

<shrug> There's no great way to do this.
Parentheses around the longer expression work.
error = goodix_i2c_read(ts->client,
(GOODIX_READ_COOR_ADDR +
1 + GOODIX_CONTACT_SIZE),
Exceeding 80 columns may be better.
Leaving it alone would be OK too.
Maybe starting with 1 to be more similar
to the below would be better.

Sometimes it's better to exceed 80 columns or
maybe use temporaries. Something like:
u8 *tmp = point_data + 1;
...
for (i = 0; i < touch_num; i++, tmp += GOODIX_CONTACT_SIZE)
goodix_ts_report_touch(ts, tmp);
