How can it break something we don't have?

Currently there is no write support for (V)FAT file systems in
mainline.

The commit removes a static variable of file scope, that was used in a
single place, where a value was assigned to it.  There was no place
anywhere in the code twhere else this variable was referenced.  So how
can this break anything?

Please elucidate.

Best regards,

Wolfgang Denk
