Re: [PATCH] drivers: misc: bmp085: remove '__init' from mp085_get_of_properties()

[Chen Gang]

It seems the "./scripts/get_maintainer.pl" is not quite precise, it
lead me to send this mail to kernel mailing list, not to drivers
related mailing list.

  [root@gchenlinux linux-next]# ./scripts/get_maintainer.pl /tmp/0001-drivers-misc-bmp085-remove-__init-from-mp085_get_of_.patch 
  Arnd Bergmann <arnd@xxxxxxxx> (supporter:CHAR and MISC DRI...)
  Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> (supporter:CHAR and MISC DRI...)
  linux-kernel@xxxxxxxxxxxxxxx (open list)

Thanks.
