When you have a truly cross-subsystem patch, it's up to you.

 - Mention both e.g. leds/net:
 - Mention neither e.g. <device>:
 - Mention the one that is most relevant

 An example of the last option might be when the lion's share of the
 changes occur in one subsystem and only header files are changed in the
 other.

In an ideal world i.e. when there are no build-time/runtime deps between
them, changes should be separated out into their own commits.

We have leds-fixes for that.
