Vladislav Bolkhovitin 6dab45204c scst: Leave out FSF mail address 
This avoids that the following checkpatch complaint is triggered:

Do not include the paragraph about writing to the Free Software Foundation's
mailing address from the sample GPL notice. The FSF has changed addresses in
the past, and may do so again. Linux already includes a copy of the GPL.
