Should send to like this ? Because I add patch for Aspeed chip:

./scripts/get_maintainer.pl drivers/misc/aspeed-lpc-snoop.c
Joel Stanley <joel@jms.id.au> (maintainer:ARM/ASPEED MACHINE SUPPORT)
Arnd Bergmann <arnd@arndb.de> (supporter:CHAR and MISC DRIVERS)
Greg Kroah-Hartman <gregkh@linuxfoundation.org> (supporter:CHAR and MISC
