[PATCH 1/2] staging: fbtft: Moves ";" from macro definition to macro usage.

[PATCH 1/2] staging: fbtft: Moves ";" from macro definition to macro usage.

[Leonardo Brás]

This makes the macro usage more like a function declaration.
Also, ending a macro definition with ";" is not
recommended by checkpatch.pl.
