Presumably this means that "ttyM0" was already registered with sysfs/udev already... In my out-of-tree driver's case, I used to use "TTY_DRIVER_NO_DEVFS" as a flag. When that flag went away, I did not put in "TTY_DRIVER_DYNAMIC_DEV" by mistake, and I got the same error as Greg C. I had to push in "TTY_DRIVER_DYNAMIC_DEV" to fix my problem... I don't know much (anything) about the isicom.c driver, so maybe I am reading something into that error that shouldn't be read into it...
