This resolves checkpatch warning "quoted string split across lines" on:
	1640: WARNING: quoted string split across lines
	1641: WARNING: quoted string split across lines

The motive to use multiple MODULE_AUTHOR statements came from this
comment from "include/linux/module.h":
	/*
	 * Author(s), use "Name <email>" or just "Name", for multiple
	 * authors use multiple MODULE_AUTHOR() statements/lines.
	 */
	#define MODULE_AUTHOR(_author) MODULE_INFO(author, _author)
