Admittedly it's not documented, but we would prefer to have some contact info
in MODULE_AUTHOR(), like an email address or a person's name.

<linux/module.h> says:

/*
 * 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)

> +MODULE_LICENSE("GPL v2");

Also, it's up to the MMC maintainer (Ulf), but the function signature
style that is used in this driver is not the preferred style.

E.g.:

+static int
+litex_set_bus_width(struct litex_mmc_host *host)
+{

should be

+static int litex_set_bus_width(struct litex_mmc_host *host)
+{

thanks.
