Rflink somfy rts invalid data

[passie]

Received my Somfy Rflink last week and it's working as expected.
Though for some reason it's flooding my logs with the following.

The "normal" RFlink doesn't have this problem.
Any clue on how to disable this debug messages as is will burn my sd card of the raspberry pi soon.
