[PATCH] Fix SGI O2 compile error in drivers/video/gbefb.c

[PATCH] Fix SGI O2 compile error in drivers/video/gbefb.c

A sysfs function call uses the wrong parameter, and thus breaks a build on
SGI O2.

  CC      drivers/video/gbefb.o
drivers/video/gbefb.c: In function ‘gbefb_remove’:
drivers/video/gbefb.c:1246: error: ‘dev’ undeclared (first use in this function)
drivers/video/gbefb.c:1246: error: (Each undeclared identifier is reported only once
drivers/video/gbefb.c:1246: error: for each function it appears in.)
make[2]: *** [drivers/video/gbefb.o] Error 1
