Add missing kernel-doc comments to prevent kernel-doc warnings:

Warning: include/linux/moduleparam.h:364 function parameter 'arg' not
 described in '__core_param_cb'
Warning: include/linux/moduleparam.h:395 No description found for return
 value of 'parameq'
Warning: include/linux/moduleparam.h:405 No description found for return
 value of 'parameqn'

Nit: The description is somewhat misleading as it mentions adding

patch and there is no need to resend it.

Looks ok to me otherwise.
