I've stumbled upon this bug, where calling i2cdetect -l prints usage and
exits. The culprit is the opt_complementary string which causes getopt32()
to bail-out if no non-option arguments are encountered.

I think the check for (argc < 1) in i2cdetect_main() got removed from
my original submission. The first patch restores it.

The second patch proposes to modify the behaviour of i2c_dev_open().

Bartosz Golaszewski (2):
  i2c-tools: fix 'i2cdetect -l'
  i2c-tools: only try /dev/i2c/* if opening /dev/i2c-* fails with ENOENT
