Can you please separate it into two patches, one for sim900.c plugin +
Makefile changes and the other for udev detection code.

oFono uses Linux kernel coding style, so please re-format your
submissions to be in-line with that style.  e.g. opening curly brace
should be on the same line as the if statement.  See
doc/coding-style.txt for additional rules above the common Linux kernel
coding style guidelines.

Please clean up the commented out areas, for example I'm pretty sure you
want this if statement not to be commented out.
