Yes, that is the (pair of) bogus line(s):

I don't know how this arrived in the config file.  Looks like something
tried to process this config file and didn't quote the entries properly.
This bit should read:

lxc.cgroup.devices.allow = c *:* m
lxc.cgroup.devices.allow = b *:* m

Interestingly, other *'s below did not get expanded...
