Subject: [PATCH] [v3] parport: mfc3: avoid empty-body warning

From: Arnd Bergmann <arnd@...db.de>

on m68k builds, the mfc3 driver causes a warning about an empty if() block:

drivers/parport/parport_mfc3.c: In function 'control_pc_to_mfc3':
drivers/parport/parport_mfc3.c:106:37: warning: suggest braces around empty body in an 'if' statement [-Wempty-body]

Remove it in favor of a simpler comment.

This one was still missing from my series to enable more warnings by default
in Makefile.extrawarn.

Greg, can you take this through the char-misc tree for 6.10?
