Hi Alex,
you should always CC the maintainers of the affected sub-systems or
architecture. Otherwise it's random if a maintainer reads through the
list and discovers your patches ;)
You can find out with get_maintainers.pl like this:
$ ./scripts/get_maintainer.pl drivers/i2c/
Heiko Schocher <hs@denx.de> (maintainer:I2C)
u-boot at lists.denx.de (open list)
