Should send to like this ? Because I add patch for Aspeed chip: ./scripts/get_maintainer.pl drivers/misc/aspeed-lpc-snoop.c Joel Stanley (maintainer:ARM/ASPEED MACHINE SUPPORT) Arnd Bergmann (supporter:CHAR and MISC DRIVERS) Greg Kroah-Hartman (supporter:CHAR and MISC DRIVERS) linux-kernel@vger.kernel.org (open list)
