I have no objections, just some comments to polish.

You've left this assignment here, but removed elm_names_size assignment below. Moving this up would look cleaner. I was thinking about some constant, but if variable assignment would be moved up and passed as a variable to malloc(), it would be less needed.

Actually, elm_desc_len is a R/W argument to ENCIOC_GETELMDESC. On entry, it indicates the space available in elm_devnames. On return, it indicates the size of the string, which is not nul-terminated. That's why I have to set it here instead of next to the calloc.
