SIGABRT when swiping finger invertedly on upek_img
On a ThinkPad X230 with
147e:2020 Upek TouchChip Fingerprint Coprocessor (WBF advanced mode), when I try to swipe my finger invertedly (down to up), I got the following error and a SIGABRT on fprintd:
(fprintd:30035): libfprint-upektc_img-ERROR **: 11:43:39.075: short scan, aborting
It seems that this is triggered by capture_read_data_cb() in libfprintd/drivers/upektc_img.c, which called fp_err (a.k.a. g_error) that calls abort().
