Hi Lautaro Javier,
Checkpatch is wrong with this proposal. The offical abreviations for 
MHz, kHz, GHz, dB and so on can remain as they are.
This is easier to read.

It is not required to add the name of the tool who found this. Much more 
important is a good description why this change makes sense...
For example:
.. to shorten code.
.. to improve readability.

Thanks for your support.

Bye Philipp
