media-ctl.c: In function v4l2_subdev_print_dv_timings:
media-ctl.c:169:32: warning: sprintf may write a terminating nul past the end of the destination [-Wformat-overflow=]
169 | sprintf(unknown, "Unknown (%u)", type);
| ^
media-ctl.c:169:2: note: sprintf output between 12 and 21 bytes into a destination of size 20
169 | sprintf(unknown, "Unknown (%u)", type);

Increase array size from 20 to 21.
